Souvik is an Applied Physics graduate student in the Atwater group since the fall of 2017. His research focuses on electrically tunable strong light-matter interactions in van der Waals systems (2D materials). More specifically, his work aims at understanding the fundamental optical properties of black Phosphorus (from monolayer to multilayers) for tailoring excitonic emission at cryogenic temperatures as well as developing room-temperature electro-optic modulators in the telecom band for reconfigurable beam shaping (amplitude, phase, and polarization modulation). Outside the lab, he enjoys good music, food, and binging TV shows.
