Biography
Professor David C. Hutchings, FInstP SMIEEE, is a world leading expert on nonlinear optics and optoelectronic integration in semiconductors and was appointed to a personal chair in Optical and Quantum Electronics at the University of Glasgow in 2004. His research interests and experience encompasses nonlinear optics, monolithic and heterogeneous optoelectronic integration, semiconductor theory and modelling, and computational electromagnetics.
Following valuable postdoctoral experience at CREOL, Univ. of Central Florida, he held prestiguous fellowships at the University of Glasgow from the Royal Society of Edinburgh & Scottish Office/Executive (1992--1995, 2003) and EPSRC (1995--2000). He served (2005--2010) as the Head of the Graduate School (Associate Dean) in the Faculty of Engineering at the University of Glasgow, and provided leadership in Knowledge Exchange activities as the Eng.D. in System Level Integration Academic Programme Director.
He has extensive experience in successfully directing and managing research council projects as principal investigator, including leading successful collaborative experimental programmes. He has authored over 80 papers in leading, peer-reviewed journals and over 160 conference presentations.
He represented the IEEE Photonics Society on the Joint Council for Quantum Electronics and the International Council for Quantum Electronics 2007-2013. He co-chaired the Quantum Electronics and Photonics 15 conference. He has chaired technical subcommittees for CLEO and Nonlinear Guided Waves.
He enjoys hill-walking and completed all 284 Munros in 2007.

Development of an on-chip correlated photon source for quantum technologies
A key requirement for a number of proposed Quantum Technology applications, particularly in Quantum Communication, is an entangled photon source at optical communication wavelengths.
This project, to develop an on-chip source on a III-V semiconductor chip, builds on a previous collaborative project with the University of Toronto and addresses an emerging demand for low-cost, compact and flexible optical sources in the near- and mid-infrared wavelength regions. The principal advantage of the quasi-phase-matching frequency conversion approach utilised here is that the wavelength to be generated is not fixed by the bandgap of the semiconductor at the wafer growth stage, but is instead determined by lithography in the post-growth processing. We have recently demonstrated an externally-pumped continuous-wave correlated photon source in AlGaAs superlattice waveguides with a high coincidence-to-accidental ratio, and a high brightness [Appl. Phys. Lett. 103, 251115 (2013)].
The III-V semiconductor platform facilitates the monolithic integration of on-chip pump lasers. The concept of vertical integration will be explored, where a wafer is designed with multiple-layers so that the guided mode is evanescently coupled to separate gain layers. This will avoid the design compromise of having the laser and nonlinear functions in the same layers that we previously studied.
Seedlayer-free Integrated waveguide optical isolators
We have an established internation collaboration with the University of Minnesota, working towards the heterogeneous integration of magneto-optic films on semiconductor photonic integration platforms. Our recent results have shown that terbium iron garnets hold great promise as they can be crystallised by thermal annealing. This avoids the difficulties of crystallising the common used Ce:YIG, which requires a sufficiently thick seedlayer, which compromises the optical mode overlap. The student would work on the design, fabrication and optical characterisation of devices on the silicon-on-insulator platform for the key telecommunication window at 1550nm, in collaboration with Prof. Beth Stadler's group at UMN.
