In this research project, we investigate the extraordinary combination of optical and mechanical properties of single crystalline diamond for integrated nano-photonic circuits and Micro-Electro-Mechanical Systems (MEMS).
Future quantum photonic circuits, low phase noise optomechanical frequency references, and harsh environment and biocompatible sensors call for technological advances in leveraging the excellent and unique properties of single crystal diamond. Up to now prototype devices and small scale integrated has been demonstrated, but reliable large-scale and cost-effective manufacturing of single crystal diamond photonics integrated circuits still remains a significant challenge.
The goal of this project is to exploit micro- and nanofabrication techniques to efficiently harness the extraordinary combination of optical, mechanical and thermal material properties of high purity synthetic single crystal diamond at the micro- and nanoscale to engineer novel and high performance diamond photonic micro- and nanosystems. In particular, we will tackle the following challenges: (1) the preparation of large area high quality single crystalline diamond thin films on a substrate, by development of an ion implantation based layer transfer process, (2) the engineering of passive on-chip diamond photonic components, such as waveguides, interferometers, and freestanding nano-opto-mechanical resonators, and (3) develop and demonstrate on-chip diamond photonic sources.
