In 1999 the LEOS Board of Governors focused on encouraging students in their studies in electrical engineering. They established the LEOS Graduate Student Fellowship program to provide fellowships to outstanding LEOS student members pursuing graduate education within the LEOS field of interest (electro-optics, lasers, photonics, optics or closely related fields). Applicants are normally in their penultimate year of study and receive the award for their final year and must be LEOS student members. Recipients are apportioned geographically in approximate proportion to the numbers of student members in each of the main geographical regions (Americas, Europe/Mid-East/Africa, Asia/Pacific). There are 12 Fellows per year. Each LEOS Graduate Fellow receives $5000 and a travel grant of up to $2500 to attend the LEOS Annual Meeting to accept their award.
This year marks the sixth year of the LEOS Graduate Student Fellowship program, and LEOS is proud to present profiles of this year’s recipients. Each student submitted a nomination package to the LEOS Executive Office with the following information: (1) a nominating letter by a LEOS member. Where no LEOS members are able to support an application, the referees may consist of the Head of Department and one other full professor familiar with the applicant’s work; (2) a one-page statement of purpose by student describing her/his education and research interests and accomplishments; (3) the student’s IEEE member number; (4) a one-page biographical sketch of student, including all degrees received and dates; (5) one copy of student’s educational transcripts; (6) two reference letters from individuals familiar with the student’s research and educational credentials.
This year, nomination packages are due at the LEOS Executive Office by 30 May 2005, and recipients will be notified by 15 July 2005. The Fellowships will be presented at the LEOS Annual Meeting in October 2005. Please send completed package to:

Mr. Masanovic is the winner of numerous awards and fellowships including the 2004 IEEE-LEOS Graduate Student Fellowship Award and the 2003 Best Student Paper award at Indium Phosphide and Related Materials conference.

BOJAN RESAN was born in Osijek, Croatia, in 1972. He received the B.S. degree in physics at the University of Zagreb, Croatia, in 1997 and the M.S. degree in photonics and imaging from Ecole Nationale Superieure de Physique de Strasbourg, France, in 1998. During his M.S. degree he conducted research in the field of optical coherence tomography at the Institute of Theoretical and Applied Optics, University of South Paris, Orsay, France.
Bojan received the Ph.D. degree in optics at the College of Optics and Photonics / Center for Research and Education in Optics and Lasers (CREOL) & Florida Photonics Center of Excellence (FPCE), University of Central Florida, Orlando, FL in 2004. His PhD research in Ultrafast Photonics group headed by prof. Peter J. Delfyett included generation of high-power ultrashort pulses from external-cavity mode-locked semiconductor lasers, their subsequent cascaded amplification and various applications such as optical communications, bioimaging, and material processing to name a few.
One of his major contributions was developing a novel dispersion-managed breathing mode, modelocked semiconductor laser. The key advance of this work is a novel approach to drastically reshape the optical pulse shape within a round trip of the laser. The resultant operation of the laser allows one to control the physical mechanisms involved in pulse formation and shaping within the ring cavity. Intensity dependent, nonlinear effects can either be enhanced or avoided at key locations within the laser cavity to enhance the performance and output characteristics, as compared to conventional modelocked semiconductor lasers. With this approach, he has been able to generate high power optical pulses with durations of 185 fs, from an electrically pumped diode laser system. The results from his research were not only published in the leading scientific journals and presented at prestigious conferences, but has also garnered public attention owing to the work being highlighted in the popular press (e.g., Optics in 2004 issue of Optics and Photonics News, Photonics Spectra).
In 2004 Bojan joined Advanced Systems Business Unit at Coherent Inc., Santa Clara, CA. He is currently involved in the research and development of novel high-power ultrafast lasers and amplifiers and deep ultraviolet narrow-linewidth laser systems.
Mr. Resan is a member of the IEEE/LEOS, OSA and SPIE. At CREOL, Bojan has been very active in professional activities, services and CREOL events. In 2003/2004, he was elected to be the Vice-President of the IEEE/LEOS CREOL Student Chapter. Bojan has received numerous awards including SPIE 2004 Graduate Student Scholarship, IEEE/LEOS 2003 Graduate Student Travel Grant, US Corporate Travel Grant, University of Central Florida Graduate Student Travel Award to name a few.

ALEJANDRA ZAPATA was born in Valparaiso, Chile, in 1972. She is married and has a 6-year old daughter. In 1993 and 2001 she received the B Eng and M Sc degrees in Electronic Engineering from Universidad Tecnica Federico Santa Maria (UTFSM, Valparaiso, Chile), respectively. Her M Sc thesis dealt with the performance evaluation of scheduling algorithms in ATM networks using Markov Chains with rewards.
She joined the Department of Electronic in Universidad Tecnica Federico Santa Maria as a Junior Lecturer in 1997.During 1997-2000 she lectured on the topics of digital circuits design, computer architecture and computer networks and supervised final year student projects. She presented the project “Updating of Digital Systems Laboratory” to the Chilean Ministry of Education – receiving a major award equivalent to US$20,000. During this time she was also a co-researcher in the projects “Multicast Routing Algorithms” (1998-1999) and “Multicast Communication: QoS Routing and Reliability” (2000-2001), both supported by the National Research Council for Science and Technology (CONICYT) of Chile.
In 2001 the Chilean government awarded her the “Presidente de la República” scholarship for postgraduate studies abroad and in September 2001 she started research towards the PhD degree in the Optical Networks Group at University College London (UCL) under the supervision of Prof. Polina Bayvel. There, her work focuses on the dynamic allocation of resources in all-optical networks, in particular on the impact that dynamic routing has on the performance and scalability of wavelength-routed optical burst switched (WR-OBS) network architectures.
After finishing her Ph.D. studies she intends to boost the research activity in the optical field in Chile (where she will go back to work as academic staff), where this area has not been strongly developed yet.
Ms. Zapata is a Junior Member of the British Federation of Women Graduates, UK. She received the Award to the Best Student, promotion 1996 granted by the UTFSM Alumni Association, the Award to the Best Female Graduate of UTFSM granted in 1996 by Zonta International, the M.H.
