Silicon carbide and color center quantum photonics
Abstract/Contents
- Abstract
- Quantum photonics has demonstrated unprecedented ways of manipulating interaction of light and matter at the nanoscale. Using effects such as confinement of light to subwavelength volumes and the generation of hybridized light-emitter states, one can reduce power and increase speed in optical networks, manipulate quantum information, and sense biological parameters. A preference for narrow emission linewidths and long spin-coherence has drawn special interest to solid-state systems that incorporate color centers. These platforms hold a promise of novel cavity quantum electrodynamical effects, integrated photonics and spintronics. While a majority of color center findings has been obtained using the nitrogen-vacancy center in diamond, recent research efforts have focused on discovering new emitters in wide band gap substrates. Therein, silicon carbide has emerged as a color center host with outstanding optical properties. This thesis presents the development of silicon carbide and hybrid silicon carbide-diamond color center quantum photonic platforms, studied through modeling, nanofabrication, and confocal spectroscopy. This includes our pioneering demonstrations of high quality factor and small mode volume microresonators in cubic silicon carbide (3C-SiC), such as photonic crystal cavities at telecommunication wavelengths and microdisks in the visible and near infra-red. Next, we have developed a scalable and efficient photonic design for spintronics at the single emitter/quantum bit level implemented in hexagonal silicon carbide (4H-SiC). We have also utilized the refractive index similarity between diamond and silicon carbide to enhance silicon-vacancy and chromium center emission in nanodiamond. Finally, the thesis introduces the model of a nanocavity containing multiple color centers that exhibit collective cavity quantum electrodynamical effects, and discuss how this regime could be reached experimentally.
