Diamond Device Fabrication for Quantum Information Processing and Sensing
The nitrogen vacancy (NV) center in diamond has in recent years emerged as one of the most promising systems for quantum information processing and sensing applications. In this presentation, I will talk about my work done during the past few years on producing diamond thin membranes and developing methodology for fabricating photonic devices on thin membranes. Also, I will talk about scalable fabrication of photonic devices from commercially available bulk diamonds. Optical and spin characteristics of these resultant devices will be discussed. In particular, we are able to enhance the zero-phonon line emission of a single nitrogen vacancy center using a photonic crystal cavity and improve the broadband photoluminescence collection efficiency through a bullseye circular grating.
