I am an experimental Physicist engaged in nanofabrication of optical materials for light control. I use Laser Interference Lithography, E-beam lithography, reactive ion etching and cost-effective self-assembly, nanopatterning, imprint patterning, soft lithography, and physical vapor deposition techniques as tools to fabricate periodically structured materials. I am an expert in fabricating photonic crystals that operate in the visible, ultraviolet, and deep ultraviolet wavelength region. Using photonic crystals I manipulate the excited-state lifetimes of emitters in organic or inorganic materials. This is useful in realizing efficient light-emitting devices. While my research on deep ultraviolet photonic crystals paves the way forward for the development of wavelength-selective devices operating in the deep ultraviolet. Nanopatterning techniques using photonic crystals hold a lot of promise for large-area structured material fabrication that is effective for energy harvesting and sensing applications. At IISc. I am fabricating 1-D and 2-D gratings by laser interference lithography technique for guided-mode resonance devices and related applications as sensors and detectors. I am developing photonic crystal cavities using E-beam lithography techniques for infrared detector applications.
