Santanu Manna received a B. Sc. Degree in Physics from the University of Calcutta in 2006 and an M. Sc. Degree and Ph.D. Degree in Physics from the Indian Institute of Technology Kharagpur, India, in 2008 and 2014, respectively. As a visiting postdoc fellow, he joined the NanoLab in the Department of Physics, University of Trento, Italy, to work with Prof. Lorenzo Pavesi on silicon photonics during 2014-2015. Later, he joined the Center for Quantum Devices, ECE Department, McCormick School of Engineering at Northwestern University, United States as a postdoctoral fellow to work on InP-based quantum cascade lasers with Prof. Manijeh Razeghi during 2016-2018. Later, he joined the Institute of Semiconductor and Solid State Physics, Johannes Kepler University Linz, Austria as a postdoctoral researcher in 2018 to work with Prof. Armando Rastelli on III-V quantum dot-based quantum single/entangled photon emitters. In August 2022, he joined as an assistant professor at IIT Delhi. As a whole, his research interest lies in the epitaxial growth by molecular beam epitaxy, processing, and measurements on III-V semiconductor (GaAs, InP) based quantum devices like single/entangled photon emitter for quantum communication, quantum cascade laser-based frequency comb and THz emitter for recognizing different molecular fingerprints. He also keeps an interest in Si-based light sources, near-infrared detectors, and nonlinear properties of waveguides, which was the preliminary work with his Ph.D. supervisor Prof. Samit K Ray in IIT Kharagpur, and postdoc advisor Prof. Lorenzo Pavesi during his NanoLab visit. Presently he is working on the blinking-free quantum dot as an entangled photon source for quantum key distribution.
