QualificationsPh.D., Scuola Normale Superiore (Italy), Physics, 2008. M. Phil, University of Kerala, Physics, 2002. B. Ed, University of Kerala, Physical Science, 2001. M.Sc., University of Kerala, Physics, 2000. Expertise and Research InterestsMy research experience is in two different areas: 1. Semiconductor optics: Realizing the unprecedented light-matter coupling christened as "ultra-strong coupling" in the intersubband resonators. Femtosecond manipulation of light-matter interaction in intersubband microcavities. 2. Functional nanoceramics and dielectrics: Synthesis and characterization of Alumina-silver(metal-ceramic) nanocomposites and investigation of the electrical properties employing electrochemical impedance spectroscopy and thermal properties using photo-acoustic technique. Probing the surface hydration-dehydration and their impact in the electrical response of low-dielectric constant silica aerogels using impedance spectroscopy. Future ResearchMy future research interests include: * Light-matter interaction in photonic-crystal nanocavities * Optical storage and manipulation in photonic crystal nanocavities * Single photon detectors for mid-infrared & THz frequencies * Bose-Einstein condensation of intersubband polaritons Industrial Relevance1. We have experimentally demonstrated world's fastest optical-switch ever(Nature 458, 178, 2009), by the all-optical control of intersubband polariton coupling. This concept can be engineered to realize next generation sub-10 femtosecond optical modulators for telecommunication. 2.The strong-coupling of intersubband absorption planar microcavity modes can QWIPs (Quantum Well Infrared Photodetectors) with very low doping density and still having very good absorption; which may lead to high temperature operation of QWIPs.
