报 告 人：Teh Peh Chiong，副教授，马来西亚拉曼大学
报告题目：High Power Fiber LaserApplications
Dr. Teh Peh Chiong is currently theattached to the engineering department in a reputable private university inMalaysia. He obtained his PhD from Optoelectronics Research Centre, Universityof Southampton in 2003, specializing in the area of Optical Communication.Since returning from the United Kingdom after his PhD, he started hiscareer in a research laboratory before moving to the manufacturing industry forseveral years. His current research focuses on advanced embedded systems designusing microcontrollers and FPGA, and also into optoelectronics design for highpower laser systems. Dr Teh has published over 40 papers in various IEEEinternational conferences and journals, with more than 13 years of experiencein research, training and consultancy. Through his vast technicalexperience, he has worked on various research and seed grants such asCradleFund and the MOSTI Technofund grants. Dr Teh has been providingconsultancy on technical matters to various companies in Malaysia, from SMEs tolocal multinational companies. He has been giving technical trainings formany years in area of electronics, optoelectronics as well as in the FTTHrelated topics.
The explosivegrowth of fiber optics technology in optical communications has seen manyadvancements in miniaturisation, improvements to laser packaging technology andcost of laser sources. Demand for Ghz rates and picosecond pulses have madegain switching of semiconductor laser mechanism an attractive method to producethe required picosecond pulses due to its simplicity, versatility, low-cost andhighly fiberised system. Conventional means to obtain such pulses will beeither through mode-locking or direct/external modulation. However, suchmethods are increasing difficult (lack of standard components availability) andhigh cost if the laser source is operated in the 1um region (away from theoptical communication bands). Also, such methods also lack the ability tocontrol the pulse waveforms. The research here will focus on the development ofthe driving electronics and control system required to drive the fiber lasersystem through direct modulation. Next, we will demonstrate severalapplications which used the pulse waveform patterning approach.
