Welcome to my homepage!
I am Dr. Chinmay Khandekar. You will find here a compilation of my current and previous research works with collaborators, and other useful resources
related to optics and photonics. This research work focusses on fundamental understanding of light and using that to advance technology applications such as photovoltaic energy harvesting, imaging, light sources, material characterization and metrology techniques, cameras, information display technologies, and micro/nanoscale heat management solutions.
I am also interested in curiosity-driven fundamental exploration into topics that are not necessarily trendy, but may be important. Even though their usefulness in not immediately obvious, they can open doors to wonderful possibilities in the future. Some of the work described here has this long term vision. Feel free to leave a question or feedback, and don't hesitate to contact if you would like to work with me on interesting problems.

Thermal memory to store information as temperature
Nonlinear upconversion of frequency-selective thermal radiation
We show that the resonantly enhanced nonlinear upconversion of light can be utilized to enhance thermal radiation at frequencies where it is otherwise exponentially suppressed because of the blackbody distribution. Upconversion of thermal radiation is relevant for thermal energy harvesting technologies.
We note that the impact of optical nonlinearities on thermal radiation was never explored before. This topic requires careful theory development which is consistent with thermodynamic laws. Our work is based on thermodynamically consistent theory modelling.
