Professor Eric Larkins is the Head of the Photonic and Radio Frequency Engineering Laboratory, whose research activities include High-Power Optoelectronics, Photonic Integrated Circuits and RF Devices, Circuits and Materials. The research activities of the Photonic and Radio Frequency Engineering Group are also closely linked to those of the University of Nottingham Institute for Materials Technology and include collaborations with the School of Physics and Astronomy and the iBIOS institute. Professor Larkins received the BS degree in electrical engineering with distinction from Cornell University, Ithaca, New York, USA in 1980, where he also became involved with GaAs-based semiconductor materials and devices. He received the MS and PhD degrees in electrical engineering with a physics minor from Stanford University, Stanford, California in 1985 and 1991 respectively. He pursued his doctoral research on light-emitting heterostructure thyristor switches and molecular beam epitaxy, receiving full support from 1984-5 as a Sold State Affiliates Fellow and from 1985 as a Kodak Fellow. He joined the Explorative Technology Group at the Fraunhofer Institute for Applied Solid State Physics in Freiburg, Germany in 1991, where he worked on high-speed semiconductor lasers, InGaAs/GaAs MSM photodetectors, 3-5um and 8-12um intersubband photodetectors, and optical modulators. At the Fraunhofer Institute, Professor Larkins and his colleagues led the development of currently accepted MBE growth techniques for highly-strained pseudomorphic InGaAs/GaAs quantum wells and achieved record direct modulation bandwidths (>40GHz) with lasers made from these materials. He joined the School of Electrical and Electronic Engineering at Nottingham as a Lecturer in October 1994 and was appointed Reader in 1998 and Professor of Optoelectronics in 2002. He is the author if two US patents relating to optical thyristor switches and switching circuits and co-author of a German patent relating to a mid-infrared tunneling intersubband infrared photodetector. He is an active member of the Photonics21 European Technology Platform, serves on the steering committee of the International Conference on the Numerical Simulation of Optoelectronic Devices (NUSOD), and co-organiser of the International High-Power Diode Lasers and Systems Conference. Professor Larkins is also a senior member of the IEEE. Professor Larkins’ research activities at Nottingham have included high-speed and high-brightness semiconductor lasers, dilute nitride semiconductors, the design and fabrication of nanophotonic devices and photonic integrated circuits, nano-biophotonics and the inclusion of nonlinear optical and non-equilibrium carrier/phonon dynamics in practical device simulation tools. These activities have involved significant international collaborations, including nine European research grants. His future research directions include innovative nanophotonic device concepts (e.g. exploiting resonantly-enhanced nonlinear optical and optomechanical light-matter interactions) and nanophotonic integrated circuits for applications in biophotonics, all-optical signal processing and photonic-electronic convergence.
Professor Eric Larkins is (or has formerly been) affiliated with Nottingham-high-power-optoelectronics-university-of-nottingham, Photonic and Radio Frequency Engineering Group, University of Nottingham and University of Nottingham.
