Passive waveguide development for integration of GaN laser devices

This project will take existing capability in GaN lasers and develop passive optical waveguides suitable for hybrid integration of these lasers. The heterogeneous integration of visible laser sources is useful in a number of application areas, for example, a coherent detection system at blue wavelengths could be used for underwater LIDAR. Functionalities such as on-chip filtering, locking, wavelength stabilisation, coherent detection are currently performed off-chip resulting in increased size and complexity or are currently not possible. The PhD will develop capability initially in waveguides focusing on deposition and etching of suitable materials to form waveguides and then moving towards integrating optical devices for use at UV to green (350-500nm) wavelengths. The project will involve industrial partner Kelvin Nanotechnology and the fabrication will be performed in the James Watt Nanofabrication Centre.
