    Funded PhD Project (European/UK Students Only)

Project Description

Vertical-cavity surface-emitting lasers (VCSELs) are high-speed, compact (low cost) laser diodes used in laser printing, datacoms and other applications. However, their implementation in the sensing and 3D imaging functions of smartphones has recently transformed the VCSEL market.

The project will build on successful collaborative work between IQE and Lancaster developing telecoms wavelength (1300 nm) GaSb quantum ring (QR) VCSELs. The objective is to push the emission wavelength further into the infrared to reach the crucial >1400 nm wavelength range for ‘eye-safe’ VCSELs to be used in the next generation of proximity sensing, gesture recognition, 3D imaging and LiDAR devices for consumer and automotive applications. The student will receive comprehensive training in both academic and industrial contexts, leading to the design, growth, processing and operation of >1400 nm VCSELs and VCSEL arrays.

The Physics Department is holder of an Athena SWAN Silver award and JUNO Championship status and is strongly committed to fostering diversity within its community as a source of excellence, cultural enrichment, and social strength. We welcome those who would contribute to the further diversification of our department.

Interested candidates should contact Prof Manus Hayne for further information. For general information about PhD studies in Physics at Lancaster please contact our postgraduate admissions staff at . You can apply directly at stating the title of the project and the name of the supervisor in your application.

Closing Date
Applications will be accepted until the post is filled.

Funding Notes

A prestigious EPSRC ICASE PhD studentship is available, starting 1st September 2020. The 4-year scholarship, incl. fees, will be supplemented by a contribution from IQE to the stipend and research costs. Funding is available to citizens of the UK and the European Union (Subject to residency status)
