个人简介
Dr. Subhasish Chakraborty is a Senior Lecturer (Associate Professor) in the Materials, Devices and Systems (MDS) Research Division (Electrical and Electronic Engineering) and a member of the Photon Science Institute. Dr. Chakraborty’s research programme encompasses theory, simulation, nanofabrication and measurement of aperiodic lattices as applied to silicon nanophotonics, THz quantum cascade lasers (QCLs) and graphene, which is directly aligned with the 'Atoms to Devices' strand of the Henry Royce Institute (HRI). As sole-PI, he previously led the EPSRC grant “Aperiodic Lattices for Photonic Engineering of THz QCLs” (EP/G064504/1), a follow-on EPSRC grant, and an international researcher grant from HMGCC. His research led to several “World First” results: the first integrated tunable graphene laser (Science, 2016); the first electronically tunable THz-over-Fibre (ToF) system (THz mixer and optical fiber coupled THz mixer, US Patent Application 0248047, 2015; Opt. Exp., 2017; Appl. Phys. Lett. 2017 (published as Editor’s pick); first electronically tunable THz QCL PICs (Optics Letters, 2021; Optics Express, 2016; IEEE Phot. Tech. Lett. 2016; Appl. Phys. Lett. 2013(i); J. Appl. Phys. 2013; Appl. Phys. Lett. 2013(ii); Opt. Exp., 2012; Appl. Phys. Lett. 2012).
Dr. Chakraborty’s lab has state-of-the-art capabilities for testing high-precision spectra for quantum nanodevices with cryogenic capability. He envisages to integrate terahertz opto-plasmonic graphene chips with QCLs alongside active and passive photonic crystal optical elements, to provide high-complexity and important on-chip photonic networking and information processing functionalities, thereby creating a flexible and powerful terahertz-frequency quantum technology platform, to enable high-density scaling of opto-plasmonic integrated circuits and quantum networks.
Dr. Subhasish Chakraborty obtained his first class Bachelor of Science degree in Physics and subsequent Bachelor of Technology degree in Radio-Physics and Electronics from the University of Calcutta, India (1991-1997). His research career began as a Research Engineer with Philips Telecommunications. At Philips (1997-1998) he developed high-frequency electronic circuits and phase-lock-loop synthesizers for application in private mobile radios, base stations and systems. In 1998 he went to the University of Cambridge as a Cambridge Commonwealth Trust Scholar, where he obtained his post-graduate degree in Microelectronic Engineering and Nanophotonics jointly with the Cavendish Laboratory (Department of Physics) and the Department of Engineering. Following doctoral (1999-2003) and post-doctoral research at the University of Cambridge (2003-2005) and at the University of Leeds (2005-2007), he then moved to the University of Manchester as a Lecturer to develop THz QCLs and associated nanophotonics and plasmonics technologies (2007).
Dr. Chakraborty has served as a referee for the UK and European Research Councils and as an external PhD examiner for the Universities of Cambridge, Essex and Kent. He is a life-member of the Optical Society of America (OSA).
