University of Southampton Optical research center

Description of the organisation


The University of Southampton’s Faculty of Physical and Applied Sciences is recognized as a world-leading research centre in the areas of photonics and nano-electronics. The ORC is an interdisciplinary research centre with a 45-years track record of pioneering contributions in the field of optoelectronic technology and its applications. Its mission is to combine focused, application-oriented research with fundamental studies into the generation, transmission and control of light.


Role in the project


In COSMICC, the ORC will be responsible to lead WP COMP (WP2) and the development and fabrication of a novel SiGe deposition technique for the fabrication of ultra-low power passive and active devices. The ORC will also collaborate on the design of silicon based low power capacitive modulators.

Key people involved

Dr Frederic Y. Gardes–FYG is senior lecturer at the Optoelectronics Research Centre (ORC). FYG’s previous research covers silicon photonics and in particular high-speed active optical devices in silicon and germanium. In 2005 FYG initiated work on silicon optical depletion modulators and was the first to predict operation above 40GHz. In 2011 FYG and his collaborators demonstrated optical modulation in Si of up 50 Gb/s and a 40Gb/s modulator with a quadrature Extinction Ratio (ER) of 10dB setting a new state-of-the-art performance in terms of both speed of modulation and extinction ratio. FYG recent work focuses on tuneable crystalline SiGe on insulator for photonic and electronic devices and includes the first demonstration of multiple crystalline SiGe on insulator wire of different concentration on a single chip using a single deposition process. He is also involved in the development and fabrication of photonic crystal slow light and cavity modulators, Si/Ge QCSE devices, Germanium and defect induced detectors in silicon and active device integration in group IV materials. FYG has more than 10 years’ experience in the field of group IV photonics, has authored more than 125 publications, 5 book chapters and 6 patents in the field of Silicon Photonics.
