PhD Studentship: Quantum Well Membrane Laser Integrated With Metasurface

PhD Supervisor: Dr Bruce Ou

Supervisory Team: Dr Bruce Ou, Prof Vasilis Apostolopoulos

Project description

The University of Southampton is expanding its PhD research in the area of Quantum Technology Engineering. In addition to the research project outlined below you will receive substantial training in scientific, technical, and commercial skills.

Membrane quantum well waveguide lasers are a more flexible route to hybrid silicon/III V laser structures in which a III V quantum well membrane laser is contact-bonded onto the surface of silica on silicon substrates (see Optics Express 30, 32174 (2022)). We have the capability to release these membranes and position them in the integrated photonics cleanroom. The membrane quantum well lasers can provide lasing in-plane as a single laser or an array of coherent lasers without the use of an external cavity. They show the potential to be integrated with silicon photonics as the light source. Here we want to combine these laser sources with meta-surfaces. Meta-surfaces, harnessing subwavelength 2D nanostructures, commonly referred to as meta-atoms, arranged in either a periodic or aperiodic fashion, have garnered growing interest for their extraordinary ability to control light in both classical and quantum light (see Nature Photonics 15, 327 (2021)).

This PhD project will focus on developing the quantum well membrane laser integrated with meta-surface to manipulate the emission properties such as direction of emission, coherence, polarisation and so on.
