1.  Prof. Sanjay Krishna, Univ of New Mexico, USA
Invited Talk: Bio Inspired Infrared Retina Using Superlattices and Quantum Dots
Speaker Biography: Sanjay Krishna is a Professor in Electrical and Computer Engineering Department at the Center for High Technology Materials at the University of New Mexico. Sanjay received his Masters in Physics from the Indian Institute of Technology, Madras in 1996, MS in Electrical Engineering in 1999 and PhD in Applied Physics in 2001 from the University of Michigan, Ann Arbor. He joined the University of New Mexico as a tenure track faculty member in 2001. His present research interests include growth, fabrication and characterization of selfassembled quantum dots and type_II InAs/InGaSb based strain layer superlattices for mid infrared detectors. Dr. Krishna has received various awards including the Gold Medal from IIT, Madras, Early Career Achievement Award from SPIE, NAMBE and IEEE-Nanotechnology Council and the UNM Teacher of the Year Award. Dr. Krishna has authored/co-authored more than 200 peer-reviewed journal articles (h-index=29) and has six issued patents. He is a fellow of SPIE and a senior member of IEEE.

Summary: Infrared detectors operating in the 3-20 μm are important due to three main reasons. Firstly, the atmosphere is transparent in the two bands referred to as mid wave infrared (MWIR, 3-5 μm) and long wave infrared (8-12 μm) making it possible to see through fog and smoke under poor visibility conditions. Secondly, a lot of chemical species have characteristic absorption features in this wavelength range making these detectors vital for remote sensing and stand off detection. Finally, there is blackbody emission from living objects at these wavelengths making it possible to use them for "night vision" and thermography applications such as surveillance and medical diagnostics. In this talk, I will try and look into the crystal ball to make predictions about the fourth generation of infrared detectors. Using the concept of a bio-inspired infrared retina , I will make a case for an enhanced functionality in the pixel.
