Semiconductor photonics is a thriving area of research, offering optoelectronic solutions for a wide range of applications extending from telecommunications to medicine and sensing. Within this field, a subdivision that is gaining increased momentum is semiconductor nonlinear photonics as the materials display a number of important nonlinear effects that can be used to generate and process signals at ultrafast speeds.
Our research focuses on the development of novel semiconductor waveguide platforms; from the design and characterisation stage, through to the demonstration of practical all-optical nonlinear devices. We investigate devices fabricated both from conventional planar waveguides on-chip as well as those based on an emerging platform that incorporates semiconductor materials directly into the cores of optical fibres. In particular, the semiconductor fibre platform offers a unique possibility to seamlessly link semiconductor technologies with the silica fibre infrastructures that are used to transmit light around the globe.
Specific topics of interest are:
- nonlinear waveguide optics
- silicon photonics
- novel material fibres
- tapered optical fibres
- optical resonators
