After joining IIT Delhi in 2005, Prof. G. Vijaya Prakash initiated the new research field, “Nanophotonics”: the study of nanostructures in photonic environment. His research interests span quantum functional materials, nonlinear optics and glass photonics. One of his extensive two decades long contributions is in the field of inorganic-organic hybrid perovskites, witnessed the commercial realization of next generation solar cells and LEDs. He is one of few initiators of research on photonic crystals in India, specifically focusing on experimental realization of electron-photon strong coupling and nonlinear device methodologies. He is widely known for nonlinear rare-earth spectroscopy/imaging of specialty glasses and phosphors for optoelectronic devices. Some of his notable research works are in demonstrating optical gain from silicon nanocrystals, shortest confocal laser cavity for atom manipulation and strong coupling, low-cost SERS substrate commercialization. He has been a recipient of research awards from UKIERI (UK), Royal Society (UK), INFM (UK) and IIT Delhi (‘High Impact Research Award’). He was instrumental in establishing DST-FIST Ultrafast Optics Lab at IITD. So far, he has guided/guiding 25 Ph.Ds and guided more than 40 post graduate students. His scholarly work is evidenced by more than 250 scientific journal publications with more than 6200 citations, h-index of 47 and i10-index of 130. His research has been recognized internationally as top 2% world scient
