About Us

CORNERSTONE (Capability for OptoelectRoNics, mEtamateRialS, nanoTechnOlogy, aNd sEnsing) is an EPSRC funded project aimed at establishing Silicon Photonics fabrication capabilities that can support photonics research in the UK, and beyond.

A general overview of the CORNERSTONE project and its capabilities can be downloaded below.

There are three UK academic institutions involved as capability providers:

  • University of Southampton (wafer-scale processing)
  • University of Glasgow (chip-level processing)
  • University of Surrey (ion implantation)

University of Southampton
The Silicon Photonics Group (www.siliconphotonics.co.uk) was formed by Professor Graham T. Reed at the University of Surrey in 1989.

The group carried out the original work upon which the first company in silicon photonics was built, Bookham Technology (now Oclaro), founded by Reed’s PhD student, Dr Andrew Rickman OBE.

Over the last 27 years, the group has made a significant contribution in the field of silicon photonics and reported many world’s first results, most notably in waveguides, optical modulators and detectors, couplers, filters, multiplexers, and transceivers. From 2012, the group has been based at the Optoelectronics Research Centre (www.orc.soton.ac.uk), University of Southampton (www.soton.ac.uk), UK. We have access to outstanding fabrication and characterisation facilities. We fabricate our photonic devices in the Southampton Nanofabrication Centre (www.southampton-nanofab.com), a state-of-the-art facility for microfabrication and high-spec nanofabrication, one of the premiere cleanrooms in Europe.

University of Glasgow
The optoelectronics group (www.gla.ac.uk/schools/engineering/research/divisions/ene/researchthemes/opto) is one of the most long established research activities in the University of Glasgow. The group have been responsible for many breakthroughs in integrated optics and semiconductor laser devices, leading to many successful spinout activities including Gemfire, Intense and Cascade.

The group benefits from the James Watt Nanofabrication Centre in the University of Glasgow, its own excellent test and measurement facilities, and a great many collaborations in the UK and overseas.

The University of Glasgow is home to the James Watt Nanofabrication Centre (JWNC), a 1350 metre square clean room facility featuring world-leading electron beam lithography capability. This is complemented with a variety of dry etch reactors, comprehensive optical photolithography and nano-imprinting facilities, metal and plasma depositions, and a full range of support facilities for the design and fabrication of integrated photonic devices, including computational modelling and characterization tools. Within the CORNERSTONE project, the University of Glasgow will provide fabrication capabilities and expertise with a focus on high resolution patterning and chip level processing.

University of Surrey
The Ion Beam Centre (IBC) at the University of Surrey (www.surrey.ac.uk/ati/ibc/) is a National Facility supported by the Engineering and Physical Sciences Research Council (EPSRC).

The IBC aims to promote and facilitate world class research in the field of ion beam applications for the UK academic and industrial communities.

The IBC allows users to undertake a wide variety of research using ion implantation, ion beam analysis (IBA) and microbeam analysis. The IBC also has extensive processing and characterization facilities.
