Silicon photonics for application in Optical Coherence Tomography (OCT) systems

Optical Coherence Tomography (OCT) is a non-invasive imaging technique commonly used to generate cross-sectional views of the retina.  Most OCT systems are based on free-space and optical fibre components to perform the interference and measurement of light signals from the imaging system. Integrated optics and silicon photonics in-particular, offer an attractive means for miniaturisation of these optical components, alongside enhanced mechanical stability, and manufacturing cost reduction compared to traditional fibre-based OCT systems.  In this project the University of Strathclyde and Optos Plc. will develop compact photonic chips for use in OCT systems.
