PhD Studentship: Mid-Infrared Silicon Photonic Devices for Environmental Sensing and Medical Applications

Supervisors:Professor Goran Z. Mashanovich

Silicon Photonics is currently one of the most buoyant photonic research fields driven mainly by application in optical interconnects, particularly in data centres. However, there is plethora of other areas such as environmental sensing, medicine, security, communications, or astronomy where silicon photonics can find application. For example, many gases that we need to detect or monitor in our environment have bands of absorption lines in the mid-infrared wavelength region (3-20 μm), hence mid-infrared spectroscopic sensing systems can be used for the detection of specific gaseous species. Currently available systems are either table-top-size instruments or composed out of discrete opto-electronic components. Therefore, they are expensive, not handheld, and power hungry. Integration on silicon will deliver increased functionality and performance as well as reducing power consumption and cost. Such integrated systems may be ubiquitously deployed in industrial process control, monitoring environment and probing exhaled breath for disease markers. Photonic integration on a silicon platform can leverage the huge investments made in CMOS fabrication technology in order to realise photonic integrated circuits for sensing applications.

The project will investigate realization of such sensors based on silicon and germanium platforms. It will involve design of photonic devices using commercial and in-house photonic and electronic simulation packages, fabrication of the devices in the state-of-the-art Zepler Institute Cleanroom Facilities (http://www.zeplerinstitute.com/facilities ) at the University of Southampton, UK, and characterisation of the fabricated devices in the silicon photonics laboratories. It will also involve integration of both passive and active photonic devices, interdisciplinary work within the Silicon Photonics Group at the Optoelectronics Research Centre (ORC), Southampton, and interaction with our academic and industrial collaborators.

A fully funded PhD place on this project is available for UK applicants. Students from overseas who have secured external funding are also welcome to apply. Students with a background in engineering, physics, materials science, chemistry or biology, and an interest in photonics would be a good fit to this exciting project area. In addition to experimental work, computational modelling and data-analysis will be key aspects. A visit to meet us is recommended and phone / Skype interviews are also possible if necessary.

The Silicon Photonics Group is the leading silicon photonics group in the UK and one of the best in the world. The group’s current funding is in excess of £25 million. APhD here has enabled our past graduates to make successful careers in academia, in national scientific laboratories, and as scientists or business leaders in industry.
