New platforms for the generation and extraction of single photons
Abstract/Contents
- Abstract
- At the core of next generation computing and communication paradigms lies the burgeoning field of quantum information science, which involves the encoding, communication, manipulation, and measurement of information using quantum-mechanical objects. One key example is quantum cryptography, which relies on quantum key distribution protocols to ensure secure communication channels. A vital enabling technology for this application is the single photon source. This thesis explores platforms for on-chip generation and extraction of single photons. First, we demonstrate a hybrid metal-dielectric nanocavity coupled to a single quantum dot that emits single photons directly into free space. In introducing this nanocavity, we conduct a detailed exploration of the design and subsequent nanofabrication of the device. Then, we introduce the design of a platform for high-purity single photon generation based on a waveguide with a partially transmitting element coupled to a photonic crystal cavity. This system generates single photons in an integrated fashion and without loss, allowing for further processing on a single chip. Finally, we test a method for angled fabrication of devices using a focused ion beam (FIB) system. We probe the feasibility of this technique in two ways: (a) undercutting of a nanobeam in 4H-SiC, and (b) angled milling of high-efficiency grating couplers using inverse design to convert from on-chip to free-space and vice versa. Taken together, we hope these individual advances provide a framework upon which to build in order to move closer to scalable, industry-ready single photon sources.
