Abstract:
Ubiquitous presence of III-nitride based solid state lighting has opened up III-nitrides as important materials for visible and UV nanophotonics. Nanophotonic architectures such as photonic crystals and metamaterials/metasurfaces have become key players in modern photonics. They have enabled unprecedented capabilities combined with great versatility to control various properties of light -propagation, polarization, emission, and photon statistics. Unique materials processing challenges posed by III-nitride materials motivates us to explore alternate techniques for nanostructure fabrication compared to Si and III-Vs. In this talk, I will present some of the approaches and results of III-N nanophotonics research based on photonic crystals and metamaterials performed at Sandia.
Biography:
Dr. Ganesh Subramania is currently a staff member at Sandia National Laboratories at ABQ in the Semiconductor Materials and Device Sciences department. He obtained his undergraduate degree in Electrical Engineering from the Indian Institute of Technology, Chennai, India. He obtained his Master’s in Condensed Matter Physics from Iowa State University in 1994. He obtained his Ph.D with Co-Majors in Applied Physics and Electrical Engineering in 2000 also at Iowa State University, following which he joined MIT as a postdoc. He joined Sandia National Laboratories in 2001.
Currently, his research interests encompass experimental realization and study of nanoscale structures (photonic crystals, metamaterials, and plasmonics ) for enhancing light-matter interaction and quantum information science and topological photonics. He has published over 50 publications and scientific reports with over 2500 citations (Google scholar). Ganesh is an SPIE Fellow and OSA Senior member and serves as a Chair of the annual SPIE Conference Active Photonic Platforms. He is currently also an Associate editor of SPIE’s Journal of Nanophotonics.
