Collaborating research institutes, centres and groups

Nanophotonics Group

We perform fundamental optical physics and materials research. This is critical for the discovery and development of new and improved optoelectronic technologies.

Planar Waveguide and Slab Lasers

We specialise in developing novel photonic materials, waveguide devices, and laser systems for application in remote sensing, defence, manufacturing, and metrology.

Research outputs

Fundamentally mode-locked, femtosecond waveguide oscillators with multi-gigahertz repetition frequencies up to 15 GHz
