College funded PhD Studentship in Engineering: Quantum Photonics with 2D Materials Ref: 2624

About the award

Location: Streatham Campus, University of Exeter, EX4 4QJ

Primary Supervisor: Dr Isaac Luxmoore

Secondary Supervisor: Professor Geoff Nash

Quantum Key Distribution (QKD) was first proposed over 30 years ago and provides a completely secure method of creating and sharing a cryptographic key. The ever-increasing reliance on mobile technology necessitates the integration of quantum secure communication within handheld devices and therefore requires chip-scale QKD systems. However, current technology cannot meet the requirements of such a system, where essential considerations include size and power efficiency. The key enabling technology is a highly efficient single photon source integrated within a photonic circuit and in this project we seek to develop such devices using defect emitters in two-dimensional materials. In recent experiments, single photon emission from structural defects in the crystal lattice of monolayer and few-layer hexagonal boron nitride (h-BN) has been demonstrated up to room temperature [1]. To capitalise on this potential, this project will target a detailed understanding of the emission mechanism and the ultimate aim of optimising single photon emission through the integration of 2D materials with high quality integrated photonic devices. The project will involve numerical simulations and experimental work, including both fabrication and optical characterisation. There is potential to work closely with collaborators at Hitachi Cambridge Laboratory and University of Twente and there will be opportunity to present your work at international conferences.
