Our group explores a wide range of topics related to the fundamental physics of nanostructured materials and their quantum-electronic and -photonic properties. We study the unique electronic, photonic and quantum properties of materials patterned over nanometer lengthscales and explore how sub-components can be integrated together to realise entirely new materials with emergent properties. This convergence of materials-nanotechnology, quantum electronics and photonics is strongly interdisciplinary, spanning topics across the physical sciences, as well as materials science and engineering.

Abstract: The potential of color centers in hexagonal boron nitride (hBN) for quantum technology applications has driven research to create emitters across a broad spectral range by using diverse techniques.…
Quantum 2.0 - Proceedings Quantum 2.0 Conference and Exhibition
Abstract: We present a monolithic AlGaAs/GaAs spot-size converter for InAs quantum dots integrating a PIN-diode stack. Simulations show > 99 % mode-conversion efficiency at 935 nm, enabling robust, low-loss…
Nano Letters
Abstract: Silicon photonic integrated circuits critically depend on compact on-chip light sources, for which nanowire (NW) lasers are an attractive solution. However, their practical implementation is often…
Advanced Quantum Technologies
Abstract: We explore the zero-phonon line of single photon emitters in helium-ion treated monolayer MoS2, which are currently understood in terms of single sulfur-site vacancies. By comparing the linewidths of…
