Chee Loon TanChee Loon Tan pursued his graduate studies in Prof. Boon Siew Ooi's group, and was a student member of the Center for Optical Technologies. His research interests include studies and demonstrations of a unique system of semiconductor laser devices, i.e. ultra-broadband quantum dot/dash laser diodes (BLD). During the past four years, he spent much of his time seeking to control the lasing characteristics of BLD through the use of a postgrowth disordering technique and epitaxial layer design. BLDs are diode lasers with ultra-broad lasing bandwidth, induced by collective individual modes lasing simultaneously from each active ensemble. They can provide a single-chip solution as an alternative to hundreds of present distributed-feedback and Fabry-Perot laser diodes. He has demonstrated the potential of BLDs in prototype form and reported his research results in major scientific publications. Most previous approaches required complex design and can only provide lasing window over a narrow range of light wavelengths. In his research, he has made a major contribution in this area by developing a BLD over a broad wavelength range of close to one hundred nanometers, opening the door to the control of light waves on a monolithic chip.
Chee Loon has published articles in international technical journals such as IEEE Journal of Quantum Electronics, IEEE Journal of Special Topics in Quantum Electronics, IEEE Photonics Technology Letters, Applied Physics Letters, Optics Letters, etc. His work has been featured in such publications as Virtual J. Nano Science and Technology, and Compound Semiconductor. He has presented his research in invited seminars at the Wireless & Optical Communications Conference 2009, and at the International Conference on Materials for Advance Technologies 2009. Chee Loon has also served as an active reviewer for journals, including the IEEE Photonics Technology Letters, the IEEE Photonics Journal, Optics Communications, Semiconductor Science and Technology, Journal of Crystal Growth and SPIE Optical Engineering.
He earned a B.Eng. in Electrical Engineering in 2005 from University Malaya in Kuala Lumpur, the top science and engineering school in Malaysia, where he was awarded the Shell Full Academic Scholarship.
In 2009, he was selected as the top winner of SPIE Student Fellowship, i.e. D. J. Lovell Scholarship. He received this prestigious award at the SPIE Optics + Photonics Annual Conference 2009.
Chee Loon is currently working at JDS Uniphase Corporation.
Prof. Boon Siew Ooi's research was funded through a grant from the National Science Foundation (NSF).
