Following a PhD in semiconductor ring lasers (1989-1992) at Glasgow University, UK, Thomas Krauss initiated research on planar photonic crystals in 1993. His work on fundamental concepts in photonic crystals, including his Nature paper in 1996, was pivotal for transforming photonic crystals from a scientific curiosity to the essential building block in photonics that they are today. He became a full Professor at St Andrews in 2000 where he established a 15-20 strong research group and a nanofabrication laboratory. He developed the slow light concept in photonic crystal waveguides and conducted, with collaborators, a number of seminal experiments, including work on ultrasmall switches and efficient nonlinear effects. Following 12 years of successful research at St Andrews, including being Head of School 2009-2012, he relocated with his group to York University, UK, in early 2013, where they soon completed setting up a new suite of nanophotonics fabrication and characterisation laboratories.
Christopher received his PhD from the University of St Andrews in 2009. Since then he has worked with Prof. Thomas Krauss as a Post-doctoral fellow, taking on responsibility for the day-to-day running of the microphotonics research group. In 2013, Christopher moved with Thomas to start a new research group at the University of York. While at York, Christopher has been involved in the design and building of a new state-of-the-art cleanroom facility based at the York Nanocentre, he has also been instrumental in the setting up of the new Photonics group's optical laboratories based at the Department of Physics. As part of his duties Christopher has built a proprietary reactive ion etching system based upon a design by Prof. Thomas Krauss. Christopher has expertise in many aspects of micro/nano-fabrication including both photo- and electron-beam lithography, wet and dry etching, and thin-film deposition (using both a proprietary sputtering system, again designed and built in-house and thermal/electron-beam evaporation).
Christopher is not supported by any one project grant, this gives him the flexibility to work within many areas. Recently he has worked in such varied areas as MidIR photonic crystals, On-chip quantum optics, terahertz generation, and all-silicon light emission. Christopher's other duties include the upkeep of the research group's website, general purchasing for the group, the running of both the group's cleanroom facility and photonics laboratories, the chairing of group activities such as our bi-monthly journal club and group meetings.
Donato graduated from Politecnico di Bari (Italy) with a MSc degree in Electronic Engineering in 2013 with an internship at the Microphotonics and Photonic Crystals Group at University of St. Andrews (Scotland) under the supervision of Prof. Thomas Krauss.
In January 2014 he started his PhD in the Optoelectronics Laboratory of Politecnico di Bari. His PhD research concerned the design and fabrication of an optofluidic system for optical trapping of sub-micrometer particles. In 2015 and 2016 he spent most of his PhD as a visitor in the Photonics group at York University for his experimental activities.
In January 2017, Donato joined the group as a research assistant involved in the project “Challenging the Limits of Photonics: Structured Light” funded by EPSRC. His activities concern the study and fabrication of an optical system for the control and manipulation of nanoparticles in air using optically-based techniques.
Donato’s research interests are in the field of silicon photonics, focusing on configurations and techniques proposed for the optimization of light-matter interaction with integrated photonic devices. His background is mainly concerned in the study and fabrication of photonic crystals and plasmonic nanoantennas.
Giampaolo was born in Siracusa, Sicily, Italy. He received a BSc (2013) in Physics from University of Catania, and is now studying for his Masters Degree in Physics, with a focus on Condensed Matter Physics and Nanotechnology. He is also enrolled at the Scuola Superiore di Catania, an institute within the university which offers high-level education beyond the standard college programs, an interdisciplinary environment and full scholarships to a limited number of students upon fulfillment of rigorous requirements. He is currently a visiting student within the Photonics group at University of York, working on his MSc thesis. The project is focused on the realization and characterization of a novel photonic crystal designed silicon bolometer in the near IR spectral window.
Giampaolo will start his PhD in the Photonics group in January 2016, working in the field of Biophotonics.
Lewis studied physics at the University of York, graduating in July 2015 with a MPhys degree. During his final year he worked in the Photonics group on a project to optimise Reactive Ion Etching for photonic devices. Since then he has worked with our bespoke Pulsed DC Magnetron sputtering system with an emphasis on reactively sputtered thin films. Lewis started his PhD in October 2015 within the Photonics group working on light emission from photonic crystals for the EPSRC Project “Seamless Integration of Functional Materials for Advanced Photonics (SeaMatics)”.
