Optimised Chiral Quantum Emission in Glide Plane Photonic Crystal Waveguides

This thesis presents work on the integration of single-photon emitters inside specially engineered photonic crystal structures. By describing the behaviour of confined electromagnetic fields on the size scales of photonic crystal waveguides, modifications of the crystal parameters can lead to interesting effects. The geometries of these crystals have been designed for a variety of beneficial circumstances relevant to IIIV, on-chip photonic networks, such as enhancing emitter brightnesses through the Purcell effect, and directional emission through a unique crystal geometry known as the glide plane symmetry. Specifically, the work is focussed on the study of suspended structures in order to procure highly-chiral, Purcell-enhanced quantum dots that would see plenty of interest for a quantum network. Additionally, this thesis presents an investigation into the ability to perform single electron spin initialisation within a quantum dot suspended in a photonic structure, contained within a p-i-n diode format. So far, this work has only been shown in a p-i-n-i-n format [1].
