Student Spotlight

Chee Loon Tan

Chee Loon Tan is a recent Doctoral Student in Electrical Engineering

Chee 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.
