The Quantum Optoelectronics Lab in the Department of Physics at IIT Kharagpur specializes in studying light-matter interactions in two-dimensional (2D) materials. Over the past five years, we have focused on optical anisotropy in layered van der Waals materials such as ReS2. Our research involves advanced optical spectroscopy and optoelectronic measurements with nanoscale devices.
In 2D layered materials, optical anisotropy arises from reduced crystal symmetry, which can be effectively examined through polarization-resolved optical response measurements. The presence of strongly bound, polarized excitons in these materials adds another layer of interest, enabling us to investigate the complex light-matter coupling that produces exciton-polaritons in these systems.
