Ashtosh Ganjoo, a senior research scientist with the Center for Optical Technologies, was awarded the Certificate of Excellence for his poster, "Origin of optical losses in chalcogenide glass waveguides," at the 2005 NSLS Users' Annual Meeting held recently at Brookhaven National Laboratory in New York.
Ganjoo is studying photoinduced phenomena in amorphous chalcogenides in an effort to make chemical and biosensors.
Specifically, he is developing waveguide sensors for bio-sensing that consist of a plano-convex lens for proper coupling of the light from an optical fiber into the waveguide; a waveguide containing a core, cladding and a nano-porous layer, all made from chalcogenide materials; and out-coupling grating and a quantum dot infrared photodetector on the same substrate.
In his research, Ganjoo uses the National Synchrotron Light Source (NSLS) at Brookhaven National Lab.
