Biography
A pioneer of near-infrared and visible quantum dot (QD) laser technology, Pallab Bhattacharya continues to be a leader in developing high-performance lasers impacting optical communication and medical and mobile projector applications. Prof. Bhattacharya was one of the first to demonstrate a room-temperature QD laser in 1996. He then demonstrated the tunnel injection method to enable QD lasers with high-speed modulation and high temperature stability. In 2011, he demonstrated the first nitride-based visible QD lasers with lower threshold than equivalent quantum well lasers. His 630-nm red QD laser is the longest ever emission wavelength achieved with nitride materials. His work on incorporating QD lasers on silicon substrates has important implications for realizing on-chip optical interconnections and signal processing.
An IEEE Life Fellow, Dr. Bhattacharya is a professor of electrical engineering and computer science with the University of Michigan, Ann Arbor, MI, USA.
