Department of Electrical Engineering

Santanu Manna received his B.Sc. in Physics from the University of Calcutta in 2006, followed by an M.Sc. (2008) and Ph.D. (2014) in Physics from the Indian Institute of Technology Kharagpur, India. He then pursued postdoctoral research at the NanoLab, Department of Physics, University of Trento, Italy (2014–2015), working with Prof. Lorenzo Pavesi on silicon photonics. From 2016 to 2018, he was a postdoctoral fellow at the Center for Quantum Devices, ECE Department, McCormick School of Engineering, Northwestern University, USA, working with Prof. Manijeh Razeghi on InP-based quantum cascade lasers. In 2018, he joined the Institute of Semiconductor and Solid State Physics, Johannes Kepler University Linz, Austria, as a postdoctoral researcher, working with Prof. Armando Rastelli on III-V quantum dot-based quantum single/entangled photon emitters. In August 2022, he joined IIT Delhi as an Assistant Professor.

His research interests span the epitaxial growth by molecular beam epitaxy, processing, and characterization of III-V semiconductor (GaAs, InP)-based quantum devices, including single/entangled photon emitters for quantum communication and quantum cascade laser-based frequency combs and THz emitters for molecular fingerprint recognition. He also maintains an interest in Si-based light sources, near-infrared detectors, and the nonlinear properties of waveguides — an interest that traces back to his doctoral work under Prof. Samit K. Ray at IIT Kharagpur and his postdoctoral research with Prof. Lorenzo Pavesi at NanoLab. He is currently working on blinking-free quantum dots as bright single/entangled photon sources, a fundamental building block for a range of quantum measurements.
