Personal statement

My research group has expertise in the design and micro-fabrication of Photonic Integrated Circuit (PIC) technologies across a wide range of material platforms.  We develop new materials for specialist applications and collaborate with industrial partners to ensure the future scalability and foundry compatability of these techniques.

 

Silicon PICs: I have a significant background in the design and micro-fabrication of integrated silicon photonics and have developed devices for applications from sensing and information processing, to cavity-enhanced non-linear interactions and quantum optics.  In particular I am interested in the development of scalable PICs that can be easily electronically tuned and addressed with simple fibre optics and am developing technologies to take this technology from device to systems levels.  This work is supported by strong collaboration with the James Watt Nanofabrication Centre at the University of Glasgow.  

Future Materials:  Not all optical functions can be realised with standard foundry material platforms such as silicon and InP.  We develop new material systems for specific applications, such as ultra-thin-film diamond for quantum optics, together with the advanced micro-processing required to create optical devices.  We have interests in single crystal diamond, III-nitrides and complex oxide materials.

Heterogeneous Integration:  Many integrated photonic material platforms have particular strengths (e.g. III-V's for light generation and detection) but are limited in complimentary areas.  In this work we seek to marry different materials in single systems to make best use of the material properties where they are needed in PICs.  For example, by locally bonding III-V materials to silicon waveguides, the light generation of the III-V's can be created where necessary in a low-loss complex silicon PIC.  

This technique also allows photonic integration of specialist materials like diamond with standard PIC technology, giving flexibility in circuit design and the prospect for scaling where materials are scarce and monlithic PIC technology is prohibitive.  Other areas of interest are hetereogeneous PICs for mid-IR applications.

Micro-LED imaging arrays: We are developing high speed LED displays with pixel dimensions of only a few tens of microns.  These devices are used for data transmission (Gb/s), covert imaging and the control and navigation of autonomous robotic agents without the need for electrical signal transmission links.
