Research summary

My research is focussed on a field of technology called Silicon Photonics. This is a field in which photonic circuits are fabricated in silicon. The aim is to bring photonics to mass markets, as silicon is an extremely well characterised and well understood material thanks to the years of study as part of the microelectronics revolution. Bringing photonics to silicon adds significantly to the functionality of silicon, enabling greater data density, greater bandwidth, and lower energy consumption, particularly as electronics moves to higher speeds. Applications of silicon photonics are currently focussed on "short reach" interconnect such as board to board, and rack to rack communications, such as deployed in data centres. Eventually silicon photonics may enable intra-chip communications, extending the performance of microprocessors for high performance computing applications. Success in these areas will enable additional application areas such as secure long wavelength communications and mid-infrared sensing circuits and lab on a chip. The performance of silicon photonic devices such as optical modulators is already so much better than expected that it may potentially impact long haul communications. My current work is related to improving device performance, as well as addressing some of the parts of the technology that have been neglected such as wafer scale testing, passive alignment of optical fibres to sub-micron waveguides, and multi-layer photonics.
