Research
- Nonlinear Optics: Ultrafast effects in semiconductors, optical control of multi-photon absorption, Electro-optic effects, Generation and modulation of Terahertz radiation, Supercontinuum generation in photonic crystal fibers; Ensembles of interacting solitons; Modulation instability in optical fibers; Soliton lasers.
- Condensed Matter Physics: Nano-structuring in chalcogen / chalcogenide and metal / chalcogenide multilayers; Quantum size effects and tunability of optical parameters in amorphous semiconductors.
- The nonlinear optical properties of glasses have recently become the focus of growing scientific and technological interest. In particular, chalcogenide glasses have emerged as promising candidates due to their large optical nonlinearity and sub-picosecond response time. However, they are far from being inducted into a real time application, as they are highly sensitive to bandgap light. Moreover, magnitude of the light induced effects is much larger than any other cumulative effects like thermal nonlinearity. The prime focus of my research group at IISER Bhopal is to explore experimentally the underlying phenomena behind the ultrafast nonlinear optical response of chalcogenide glasses and learn how to control, tailor and enhance them.
