Description and expertise of the organisation:
The optics group of University of Bristol comprises 7 academic members, 10 research assistants and around 20 PhD students. Bristol group is contributing into increasing requirement to broadband capacity through research into novel semiconductor lasers, wireless-over-fibre systems, optical switching, wavelength conversion and high-speed modulation. Facilities of the group include clean room for device fabrication with advanced etching and coating facilities, a focused ion-beam machine with 7 nm resolution, a state of the art electron-beam lithography system, advanced experimental kit for lasers, microcavities and optical switches.

Optics Group was involved into EU FP6 projects QAP, SECOQC, MUFINS, EQUIND, ACDET and coordinator of EU programme IOLOS and the COST288 photonics network.


Research interests / Project ideas
To find academic and industrial partners for development, fabrication, research, applications and putting into production of the new generation of 1300 nm semiconductor vertical-cavity surface-emitting lasers with internal photonic crystals. Single-mode VCSELs are compact and low-cost emitters for local fibre-optical networks. They are able to deliver transmission speeds up to 12 Gbit/s but only small transmission distances are available because their power is low. The new generation of VCSELs with internal photonic crystal is being developed and it is expected to deliver high-power, single-mode and stable radiation that could reduce mode dispersion in fibre-optical networks, increase the quality and the distance of transmission. These properties of lasers must make the entire fibre-optical network cheaper, faster and more affordable for users.

We are looking for academic and industrial partners those are able to process semiconductor laser devices, test them, put these lasers into production and provide molecular-beam epitaxial facilities for device growth.
