Project title: Laser processed Silicon/Ferroelectric photonics
Supervisor: Dr. Sakellaris Mailis
Co-supervisors: Prof. Anna Peacock, Dr. Harold Chong
This project targets the integration of silicon with optically nonlinear, ferroelectric lithium niobate crystals to produce a photonic platform that will benefit from the properties of its constituent materials.
Silicon, which is synonymous with microelectronics and more recently with integrated photonic circuits, is limited by the lack of electro-optic and second order nonlinear response. Lithium niobate has a well-established pedigree in industrial photonics because of its electro-optic and nonlinear optical functionality throughout the visible and mid infrared spectral region.
This project will produce i) laser processed silicon photonic structures on lithium niobate and ii) laser processed thin film lithium niobate on silicon substrates to demonstrate multi-functionality beyond the limits of individual silicon or lithium niobate materials.
The project will have elements of: i) materials growth (deposition of amorphous silicon and other starting materials); ii) device fabrication (photolithographic patterning and laser crystallization) of various integrated photonic components such as couplers, resonators, modulators etc; and iii) optical characterization and device benchmarking.
To discuss any details of the project informally, or to arrange a visit to meet us and see our facilities, please contact Dr Sakellaris Mailis [firstname.lastname@example.org].
The PhD programme
The ORC PhD provides a solid education for a research career. The structured first year involves attending our training programme running in parallel with carrying out your research project. This provides a smooth transition from your degree course towards the more open-ended research that takes place in the following years under the guidance of your project supervisors. We expect our students to present their work at major international conferences and to write papers in leading academic journals as their research progresses.
The ORC is a world-leading photonics research organisation of around 200 research staff and students, famous for the development of novel photonic technologies underpinned by cutting-edge research in materials. Its mission is to combine applications-led research with fundamental studies into the generation, transmission and control of light. A PhD here has enabled our past graduates to make successful careers in academia, in national scientific laboratories, and as scientists or business leaders in industry.
A fully funded PhD position is available for UK applicants. Overseas students who have secured some external funding are also encouraged to apply. EU students with no external funding may additionally contend for a small number of competitively allocated scholarships.
Entry requirements: First or upper second-class degree or equivalent.
Closing date:Applications for 2017 entry are open now; early application is strongly advised. For reasons of funding allocation, applications from international candidates should be made by 31st March 2017. UK applications are accepted throughout the year.
Duration: Typically 3.5 years (full-time).
Start date: Typically September/October (but other start dates are possible).
Funding: All fully-funded places include paid tuition fees and a tax-free bursary to cover your living expenses. Our UK-student enhanced stipend is £18,000 per annum for up to 3.5 years. The EU/International bursary is based levels set by the UK Research Councils - in 2016 this was £14,296 per annum for up to 3.5 years.
Assessment: 9- and 18-month written reports and viva voce examinations determine progression; PhD awarded after thesis submission and viva voce examination.
