Biography

Professor Simarjeet Saini joined University of Waterloo in September 2007. He did his B.Tech. (Hons.) from Indian Institute of Technology, Kharagpur in 1996 and his Doctorate from University of Maryland, College Park in 2001 under the guidance of Professor Mario Dagenais. His Ph.D. thesis was on the design and development of a new platform technology for monolithic integration of photonic devices called Passive Active Resonant Coupler (PARC).

The resulting technology led to the foundation of a start-up company Covega Corporation in Jessup, MD. Saini worked as the Lead Optoelectronics Device Engineer at Covega from Dec. 2000- Oct. 2004 and as Lead Applications Engineer from Oct. 2005-Sept. 2007. He lead the design and development of Covega’s single angled facet chips, semiconductor optical amplifiers and high power lasers. In August 2004, Saini co-founded a startup company called Altanet Communications which worked on ethernet based metro area networks with less than 5 ms restoration time using intelligence in the optical domain. He also served as a Post-Doctoral Fellow from Oct. 2004-Sept. 2005 in Professor Dagenais’ lab at the University of Maryland where he worked on biochemical sensors and optical packet routing.

Saini has been granted 5 US patents and has 5 more in various stages of application. 3 of the patents have already been commercialized. He has co-authored over 20 Journal papers and 40 conference presentations. He was granted the US Army Lab Research Fellowship from 1996-1998, a Distinguished Graduate Research Assistantship from University of Maryland from 1999-2000, and a SPIE Educational Scholarship in 1999. Besides that he was a part of a team comprising of undergraduate students in Indian Institutes of Technology, Kharagpur which received Institute of Electrical and Electronics Engineers Vincent Benedict Award in 1995 for building a smart library.
