Professor Yong Tak Lee is Korea-first leader in the epitaxial growth of compound semiconductors for optoelectronics. He has pioneered the Korean R&D activities on the development of world-first high-speed vertical cavity surface emitting laser (VCSEL) arrays and resonant-cavity enhanced photodetector (RCEPD) arrays which yielded several inventions on high-speed chip-to-chip and board-to-board optical interconnects. Over the last 25 year period, he has made many technical breakthroughs and advances in manufacture of innovative laser and photodetector technologies, including (i) monolithic integration of self-aligned micro-lenses on vertical-cavity surface emitting lasers, (ii) temperature distribution modelling and control in intra-cavity-contacted oxide-confined vertical-cavity surface-emitting lasers, (iii) geometrical optimization of high speed intra-cavity-contacted oxide-confined VCSELs, (iv) stabilisation of single-mode VCSEL operation using mode selective apertures, (v) spectral bandwidth improvement of InGaAs/GaAs resonant cavity enhanced photodetectors, (vi) wavelength tuning of resonant cavity enhanced photodetectors for bi-directional optical interconnects, (vii) molecular beam expitaxial (MBE) growth of digital-alloy multi-quantum wells, (viii) laterally coupled DFB lasers based on self-aligned metal surface gratings, (ix) stacked InAs/GaAs quantum dots with growth interruption, and (x) improvement of the optical property and uniformity of self-assembled InAs/InGaAs quantum dots. Professor Lee is a Member of the Korean Physical Society; the Optical Society of Korea; and the Optical Society of America. He was the Editor-in-Chief, Optical Science and Technology, Optical Society of Korea (2003-2004).Senior IEEE Member. He is the author/co-author of over 50 patents (granted or applied), over 100 SCI journal papers and over 150 conference proceedings.
