LEOS is proud to present profiles of our LEOS Graduate Student Fellows of 2000:


Randy A. Bartels received his Ph.D. from the University of Michigan 2002. His Ph.D. work was performed at JILA in Boulder, CO, where he worked on ultrafast laser development, coherent control of quantum systems, and the study of extreme nonlinear optical processes. Among other advances, this work led to the development of attophysics by manipulating the strong-field dynamics of atomic electron wave functions with ~ 10 attosecond precision. During his graduate career, Randy was supported by a National Defense Science and Engineering Graduate Fellowship and received numerous awards, including the IEEE LEOS Graduate Fellowship, Optical Society of America’s New Focus Student Research Award, a JILA scientific achievement award, and selection as a finalist for the DAMOP Thesis Award. Prior to graduate school, he worked in the Laser Science and Technology division at Lawrence Livermore National Laboratory designing and building diode-pumped solid-state laser systems. Randy joined Colorado State University (CSU) as an assistant professor in January of 2003. Since arriving at CSU, Prof. Bartels has been awarded the 2004 Adolph Lomb Medal from the Optical Society of America, a 2004 National Science Foundation CAREER award, and was recently named a 2005 Sloan Research Fellow in physics. His current research involves the control of molecular coherences for novel nonlinear optics and manipulation of ultrafast optical pulses, as well as development of EUV laser sources and optical systems and is funded by the NSF, the American Chemical Society Petroleum Research Fund (Type G), and the Sloan Foundation. He is a member of the Optical Society of America, the American Physical Society, Sigma Xi, and the IEEE.

The receipt of the 2000 LEOS Graduate Student Fellowship was a big boost in motivation during my Ph.D. programme. At the time of the award I had completed nearly 2 years of my Ph.D., so it confirmed that my research in the field of dynamic optical networking was both timely and state-of-the-art. I am extremely grateful to my Ph.D. supervisor, Prof P. Bayvel of University College London (UCL), UK, for proposing my name to the selection committee. In the retrospective, the fellowship lent a lot of credibility to my research, so the LEOS Annual Meeting just became the starting point from which more than 50 contributions to journals, conferences and seminars followed.
After completion of my Ph.D. in 2003 I became a postdoctoral research fellow at UCL in a collaborative Basic Technology Project concerned with the research of quantum computation, where a number of problems on the small scale occur which show striking similarities to those problems relevant in wide-area network design. Just recently I became a member of technical staff at the Deutsche Telekom research facility in Berlin, Germany, concerned with investigation of the combination of traffic statistics and core network design problems.

It was a great honour for me to receive the LEOS Graduate Student Fellowship in 2000. At that time, being a final year PhD student and finding that one’s research and hard work have been recognised by LEOS was really a big encouragement. With the financial support from the Fellowship program, it was a very enjoyable experience to attend the LEOS annual meeting in Puerto Rico to meet excellent researchers and students from all around the world. Most importantly, this award has greatly motivated me to continue my career as a scientific researcher.
Since obtaining my PhD in 2001, I have continued my research in the same Semiconductor Optoelectronics and Nanotechnology Group led by Prof. C. Jagadish, in the Department of Electronic Materials Engineering, Research School of Physical Sciences and Engineering, The Australian National University. I enjoy my work in the field of semiconductor materials and optoelectronic devices.
I would like to take this opportunity to thank LEOS again for offering such an excellent program and strongly encourage eligible graduate student members to consider applying for this award.

In 2004, I joined the Electrical and Computer Engineer-ing department of University of Cali-fornia, Davis as an Assistant Professor. After my graduation from UCLA in 2001, I spend more than three years at SDL Inc./JDS Uniphase Corporation, Gazillion Bits Inc. and Hewlett-Packard Laboratories. Currently, my research focuses on the incorporation of low-dimensional nanowire devices with conventional devices and circuit elements, employing processes compatible with mass-manufacturing. Unlike the research-based approach of sequentially connecting electrodes to individual nano-structures for device physics studies, massively parallel and manufacturable interfacing techniques are crucial for reproducible fabrication and incorporation of dense, low-cost nanodevice arrays. I have developed novel nano-device integration and mass-production techniques that are entirely compatible with existing microelectronic and photonic fabrication processes. My goals include the development of massively parallel synthesis and integration processes for nano-structures for potential applications bio-chemical sensing, nanoelectronics, nanophotonics, memory and logic devices for future computing.
In 2000, the LEOS Graduate Student Fellowship tremendously contributed to boosting my morale to strive for attaining higher and challenging goals. The meeting and subsequent ones offered me the opportunities to mingle and exchange ideas with world experts in many different fields and make new friends and future colleagues/collaborators. Many of them continue to extend their help in broadening my knowledge in the fields beyond my research interests. The award induced a lasting mark of inspiration and self-confidence deep in my heart and the sizeable cash was very helpful in taking care of many pressing needs. I am always thankful to LEOS for offering this fellowship to graduate students.

In 2002, I graduated with a PhD in Electrical and Computer Engineering from Purdue University with specialization in advanced semiconductor optoelectronic devices. My research focused on the design, fabrication, and optimization of large-area high-speed MSM photodetectors for polymer fiber-optic applications. The highlight of the work was the demonstration of a large area photodetector (diameter = 300 m) with a bandwidth of 6 GHz. From 2004-present, I am working at National Semiconductor as a Senior Device Engineer. My present responsibilities include device modeling of advance semiconductor processes for analog applications
I was fortunate to be a recipient of the prestigious LEOS Graduate Student Fellowship in 2000. The Fellowship is a very wonderful program. It provides an excellent platform for recognizing significant contributions to the research in the optoelectronics by graduate students. It has benefited me immensely by highlighting my research contributions and was very helpful during job interviews. To summarize, the Fellowship is an excellent way in which the IEEE LEOS can recognize and support the up and coming researchers who would be the milestones of the future. Keep up the good work IEEE and LEOS and thanks very much!

First and foremost, I would like to address my sincere gratitude to IEEE LEOS for giving me this opportunity to have a piece of thought on the IEEE LEOS Graduate Fellowship Award program. This award is a symbol of recognition for young researchers who have contributed significantly in the area defined by LEOS. It also has an open policy in which the award is divided into a few geographical areas that provides equal opportunity to other young researchers from developing countries like me. I felt so grateful that my research under restricted facilities was recognized by LEOS. This award has boosted my self-motivation and will always be memorized as my all-time favorite award.
Upon receiving this award, I accepted an offer from a start-up company in the United States (2001) and wasted no time in meeting the challenge with one objective that was to be a successful optical engineer. It was during my stint in the United States that I involved in the design and development of two commercial designs and numerous engineering prototypes that all related to optical amplification technologies. I also had one patent pending approval in the United States for a unique design of high-end amplifier that can self-adjust its gain shape automatically without the use of a channel monitor. Unfortunately, the optical fiber communication was no longer immortal technology in the late 2002 and due to this collapse; I opted to become a university lecturer in Malaysia. Now, I am an associate professor at Universiti Putra Malaysia and still active in research that includes but not limited to optical fiber devices, optical fiber communications and optical fiber sensors. Nevertheless, this award has significantly contributed to the recognition of my research in Malaysia whereby, I was awarded for the National Excellent ICT Teacher Award 2003. Furthermore, my university also nominated me as one of the candidates for the National Young Scientist Award 2003 which is still pending.

I received the LEOS Graduate Student Fellowship for 2000 when I was in the middle of my PhD studies in the Optical Networks Group, Department of Electronic and Electrical Engineering, University College London under the supervision of Professor Polina Bayvel. The fellowship was an important confirmation that my research in the area of multiwavelength high speed optical fibre transmission was important and relevant. The development of the reconfigurable recirculating fibre loop testbed and the investigation of fibre nonlinearities with different modulation formats propagating over various dispersion maps at 10 and 40 Gbit/s, were the most important subjects of my PhD research which resulted in 45 publications and conference presentations at all the leading international conferences such as OFC, ECOC and CLEO.. I was awarded my PhD degree in 2003 and in 2004 I received the Institute of Physics Quantum Electronics and Photonics Group PhD prize (highly commended) for ‘PhD thesis examined in 2003’.. All these achievements would have been impossible without the help of my supervisor Prof. Polina Bayvel and colleagues from the group. During this time I was also fortunate to have the opportunity to spend time as a consultant in the Photonics Systems Group at Bell Laboratories, Lucent Technologies (headed by Dr Martin Zirngibl and collaborating with S. Chandrasekhar, C.R. Doerr et al). This fruitful collaboration is ongoing.
Currently I am a Senior Research Fellow (and concurrently appointed to a Research Councils’ UK Academic Fellowship) in the Optical Networks Group, where I have a brilliant opportunity to continue my research of the fundamental effects governing high speed (> 80 Gbit/s/channel) optical transmission and all-optical signal processing.

I have been working in the group of Prof. Sergei A. Kozlov at St.Petersburg State University of Information Technologies, Mechanics and Optics, Russia since 1996 when I was a second-year student. I analyze theoretically phenomena accompanying propagation of intense femtosecond laser pulses in transparent media. In 2000, on the last year of my Masters program I was awarded IEEE/LEOS Graduate Student Fellowship. That time I should make a choice whether to continue my favorite University studies within the framework of a Ph.D. course after graduation or look for another job, most likely not purely scientific because the financial situation in Russian science was very difficult. Successfully, the Fellowship money appeared to be the base for my studies and I joined Ph.D. program in ultrafast optics. In addition, the Fellowship helped me participate in the European Conference on Optical Com-munications 2001, held in Amsterdam, The Netherlands.
In 2003 I finalized my thesis titled “Scenarios of spectral ultrabroadening of intense femtosecond laser pulses in optical waveguides” and received the Degree of Candidate of Science in Phys. and Math., which is the Russian equivalent of Ph.D. Since 2004 I am working for the Degree of Doctor of Science, the highest scientific degree in Russia similar to Full Professorship. I continue researches in ultrafast optics, supervise M.S. students and teach general physics to first-year students. I am an author and co-author of 30 papers in Russian and International scientific journals and more than 40 reports at International Con-ferences. The IEEE/LEOS Graduate Student Fellowship opened me a way to other international awards for young scientists as SPIE Educational Scholarships in Optical Science and Engineering including named Nakajima Scholarships (2001-2004) and OSA New Focus Student Award (2001). I am very grateful to IEEE/LEOS for supporting my scientific career.

I’m currently working as contract re-search fellow at the photonics research group at Aston University, United Kingdom. My research interest focuses around all-optical bit serial processing for future optical networks. Aside from academic research, I’m involved in a commercial study of existing undersea long-haul fiber systems for a startup company.
With the cash reward, I bought myself a personal computer plus accessories for my research work. For the next years ahead, I believe that assigning a mentor from the panel of judges to each future graduate student fellow would further develop the full talent and potential of these future young researchers.

Wai Mun Wong, Ph.D

I graduated from the University of Michigan, Ann Arbor in 2001, with a Ph.D. degree in Electrical Engineering. My research experience includes areas of semiconductor lasers, receiver and transceiver based OEICs, spans from design and fabrication to characterization. My PhD thesis focus was on novel transmitter research involving microcavity, quantum dot, and photonic crystal devices, which led to 37 peer reviewed journal publications, conference presentations and invited/plenary talks. The Research work on electrically injected photonic crystal light emitting devices leads to the exclusive Nature News and Views review after it was published in Electronics Letters. I received LEOS Graduate Student Fellowship award in 2000 for my outstanding academic performance and research achievement.
After my graduation, I joined CIENA Corporation, a leading company on the wavelength division multiplex (WDM) technology. I worked as a lead engineer at the Active Photonics Group, responsible for the C band tunable lasers and the OC192 transponders for the next generation ultra-high density WDM systems.
In Fall 2004, I joined the University of Texas at Arlington, as an assistant professor of Electrical Engineering. Currently, I am a faculty member at the NanoFAB center. My current research interest includes photonic crystal based semiconductor lasers and detectors, OEIC, nanophotonic and nanoelectronic based photonic IC.

My suggestions on IEEE/LEOS Graduate Student Fellowship program:
I hope the program not only recognizes the fellows’ past performance, but also provides a means for the fellows to communicate and collaborate in the long term, to share both academia and industrial experiences, to promote and stimulate creative thinking and high quality research/development. Some examples of activities:

  1. Make a special section at LEOS (night section, poster or oral) for all fellows to present their major technical achievements.
  2. Enhance the network among the fellows: Setup email list; compile fellow profiles; a dedicated weblink on LEOS student web site, social events during LEOS annual meeting for past and current fellows.
  3. How about a LEOS fellow summit every two years? LEOS fellows can showcase their achievement and update their career activities.
