The Optoelectronics Research Centre has a 40-year track record of pioneering contributions in photonics and is currently one of the largest and most dynamic research centres in this field world-wide.  The Integrated Photonic Devices Group explores the fundamentals of guided wave optics at surfaces, with applications including telecommunications, biosensing and novel light sources, and is complemented by world-class photonic materials and fabrication facilities (

The Project: Mid-infrared absorption spectroscopy is the most widely used technique for detecting the molecular signatures of an unknown sample using their fingerprint absorption. Waveguide evanescent field based spectroscopy can detect analytes at very low concentrations using their absorption fingerprints, potentially offering high sensitivity and selectivity over a wide range of compounds without labelling.

The ideal molecular “fingerprint” region for biochemical analysis is dominated by the Mid-IR spectral region from 2μm - 13μm. This project will explore novel Mid-IR waveguide based integrated photonic devices and will help realise photonic lab on-chip platform for biomedical diagnostic applications. Specifically this will involve the fabrication and characterisation of waveguides (using novel Mid-IR materials) and waveguide based devices such as ring resonators, on-chip sources and Mach-Zehnder interferometer, and their integration. The project will also involve electromagnetic modelling of some of these devices for optimising the performance and for designing photonic circuit layouts.

Supervision: This project will be supervised by Dr. Senthil Ganapathy and Prof. James Wilkinson

Entry requirements: first or upper second-class degree or equivalent

English language: IELTS 6.0, with a minimum of 5.5 in each component; for information on other accepted English Language tests, please visit

Duration: up to 4 years (full-time)

Start date: typically October 2017

Applying: For further application details please click here

Funding: Full scholarships are available for UK students. We are normally able to fund the fees of EU applicants but we only have limited funding to support living expenses. The competition for this funding is therefore tough and obtaining funding from any other source will increase chances of success. International students are encouraged to seek full or partial funding from other sources (e.g. national government scholarships, commonwealth scholarships, self-funding etc).

Contact: You are welcome to contact Dr. Senthil Ganapathy ( or Prof. James Wilkinson ( for an informal discussion. Please mention the project title and supervisors name in your application when applying online.
