Summary of project

PhD – Funded for 3.5 years.

Telecoms are an essential part of modern life for domestic, academic and industrial applications, with information networks acting as a vital channel for communication, data storage, and media access. These networks consist of lasers (emitting at 1.3 or 1.55 microns) to transmit information, silica fibres as a transmission medium, and detectors to receive the information. As a result of telecoms importance in modern life these constituents have been a focus of a great deal of research over past decades, aiming to further develop and improve upon the contemporary technology. With regards to lasers, the current technology has hit its physical limit in terms of efficiency and bandwidth.

The aim of this project is to develop entirely new telecom lasers based on existing world class compound semiconductor materials research at Lancaster University. Novel quantum structures will be investigated in order to enhance the efficiency to improve and explore the boundaries of device performance. The devices will be integrated onto Silicon to create future hybrid optical/electrical microchips. This builds on pioneering work on the implementation of compound semiconductor optoelectronic devices on Silicon recently developed at Lancaster1. The research will involve epitaxial growth and characterisation of the resulting materials using spectroscopy, electrical and structural measurements and device modelling. The research work will focus on exploring fundamental device physics as well as the fabrication and characterisation of devices.

This project is intellectually challenging and involves well-integrated elements of engineering, physics and materials science. The work will also be carried out in close collaboration with leading international research groups and industries. The successful candidate will develop a wide range of skills in materials and photonics and be part of a growing team that seeks to address industrial problems while maintaining a strong science and technology base. They will be expected to write scientific papers and present their work at national and international conferences.

Eligibility criteria: Candidates should be highly motivated and have a good undergraduate degree in a relevant subject such as engineering, physics, chemistry or materials science.

Application procedure: To apply, send a copy of your CV to Dr Peter Carrington, Engineering Department, Lancaster University by email to . Informal enquiries to this address are also very welcome.

Funding Notes

This is a 3½-year studentship, available from October 2020. It pays a non-taxable bursary of ~£15,000 per annum. To be eligible for the studentship, the funding requirements are that the candidate must either be a UK citizen or a European Union national. Overseas candidates are welcome to apply but will be required to cover the gap between home and international tuition fees.
