| Wood-Hi Cheng |
Wood-Hi Cheng is a Chair Professor at National Sun Yat-sen University, Kaoshiung, Taiwan, where he founded and became the Director of the Institute of Electro-Optical Engineering (1994–2000), and Dean of College Engineering (2002–2005). In 2007 he chaired the Southern Taiwan Opto-Electronics Center of Excellence. Presently he is a Program Director of Optoelectronics in the National Science Council of Taiwan providing research grants and direction. Prof. Cheng is a Fellow of IEEE and OSA.
While Dr. Cheng was in the United States, he contributed to the development and growth of high-speed semiconductor lasers with semi-insulating (SI) blocking layers at Rockwell International, CA. In 1987-1993, he was the first to propose and demonstrate low-threshold, high-power, and high-speed 1.3 mm buried crescent lasers with the iron and cobalt-doped SI current blocking layers. He also developed a high-power low-divergence superradiant diode at General Optronics, NJ. In Taiwan, Professor Cheng’s R&D made contributions to photonic package technology and technology transfer to industry (Quarton). Quarton then became the first solid-state laser company in Taiwan, and is currently the top-five sale for laser pointer in world since 1993. He was recipient of the IEEE Photonics Engineering Achievement Award in 2010 for design, development and commercialization compact solid-state laser modules. Prof. Cheng’s most significant R&D is the demonstration of record ultra-broadband 300-nm Cr-doped fibers (CDFs). The CDFs have been used for the first time as a broadband Cr-doped fiber amplifier (CDFA). With the help of optical-fiber system examination for the CDFA, a 40-Gb/s error-floor free data transmission is successfully demonstrated on fiber-optic transmission.
Title of Talk: The Art and Science of Packaging Photonic Devices and Modules
Prof. Cheng and his team have made milestone contributions in a series of works describing photonics packaging technology from the art and science points of view. The lecture will present the photonics packaging technology including the high-coupling packaging design of double-variable-curvature microlens employing fully automated process for higher average coupling efficiency from 980-nm lasers into single mode fibers, reduction of fiber alignment and postweld shift in laser module packaging, packaging of passively mode-locked fiber lasers employing carbon nanotubes or graphene, packaging of high-reliability glass-doped phosphor-converted high-power white-light-emitting diodes, and packaging of 300-nm ultra-broadband Cr-doped fiber amplifier for broadband transmission.

| Katsumi Kishino |
Katsumi Kishino earned his Bachelor’s, Master’s, and Doctorate degrees in Engineering from the Tokyo Institute of Technology, Tokyo, Japan, in 1975, 1977, and 1980, respectively. From 1980 to 1984, he was a Research Associate at Tokyo Institute of Technology. In 1984, he joined the Department of Electrical and Electronics Engineering, Sophia University, Tokyo, as a Lecturer. Then, he was appointed as an Associate Professor in 1986 and a Professor in 1992. He is conducting research on nitride semiconductors by rf-MBE including GaN-based nanocolumn, InGaN-based nanodevices and InN-related materials, and on novel II-VI compounds on InP substrates and related yellow-green emitters. From Sept. 1989 to Aug. 1990, he worked on the first stage of research of resonant-cavity-enhanced (RCE) photodetectors as a Visiting Associate Professor at the University of Illinois at Urbana-Champaign, on leave from Sophia University. Dr. Kishino is a fellow of the Japan Society of Applied Physics and the Institute of Electronics, Information and Communication Engineers (IEICE) of Japan, and a senior member of IEEE.
Title of Talk: GaN-based Nanocolumn Emitters and related Technologies
GaN nanocolumns, one-dimensional columnar nanocrystals, possess low dislocation and high light extraction efficiency properties; thus, the nanocolumns have a great potentiality to improve substantially the luminous efficiency in the green-to-red emission region. Periodically arranged GaN nanocolumns, in each of which an InGaN/GaN multiple quantum well (MQW) was integrated, were fabricated by a Ti-mask selective area growth (SAG) technique by rf-MBE for GaN. Using the uniform arrays of InGaN-based nanocolumns, we demonstrated successful optically pumped stimulated emissions in the blue-to-green emission range and operation of green emission InGaN-based nanocolumn LEDs; then, a novel technology for controlling the In composition of InGaN quantum wells on the same wafer was developed, which paved the way for the monolithic integration of three-primary-color light-emitting diodes.

Title of Talk: NanoSilicon NanoPhotonics
Silicon Photonics is no more an emerging research topica but is an actual technology with commercial products already available on the market. Quantum confinement of carriers or spatial localization of photonics allows dramatically enhance and widen the scope and potential of silicon photonics.
After a review of silicon photonics where the state of the art is presented, the optical properties of silicon reduced to nanometric dimensions are introduced. The use of nano-Si in silicon photonics (waveguides, modulators, switches, sources and detectors) is reviewed and discussed. Recent advances of nano-Si devices such as bio-imagers, optical resonators (linear, rings, and disks) are treated. The development of high efficiency light emitting diodes for interchip bidirectional optical interconnects is presented as well as the recent progresses to exploit nano-Si for solar cells. In addition, non-linear optical effects which enable fast all-optical switches are described. On the other hand, confinement of photons to small microresonators allows tuning the photon properties. Here also novel effects are found. Ultra high bandwidth robust optical switches for UDWDM, active suspended microdisk bistable devices, nonlinear optical generations are only few applications where nanophotonics can be appreciated.

Title of Talk: Polarization in Fiber Optics
Polarization is a paradoxical parameter in optical fiber, as it provides flexibilities in various applications, such as advanced modulation formats in optical fiber communication systems, polarization-assisted fiber sensor applications, sensitivity-enhanced biomedical applications, etc. On the other hand, polarization is difficult to control and even associated with signal degradations due to random and dynamic polarization evolutions along the fiber. Currently polarization-related impairments are among major hurdles for high performance fiber systems.
Tremendous efforts to effectively and efficiently manipulate polarization have been spent within the research and industry community. Starting from basic introduction about polarization, the lecture reviews different perspectives of polarization in fiber optics, including the polarization division multiplexing, polarization-related degrading effects and their mitigations, polarization based fiber sensor and biomedical applications, as well as polarization in nonlinear signal processing schemes. Practical issues will be highlighted. |
