Exciton polaritons in novel materials and photonic structures for nonlinear photonics

Description

One of the most sought-after properties in photonics is strong nonlinearity, the ability for particles of light to interact with one another. This can be achieved by hybridising light with matter resulting in new particles called exciton polaritons. However, existing platforms for exciton-polaritons are often limited by large linewidths or the need for cryogenic temperatures. This project aims to solve these issues by exploring new frontiers in both material science and nanophotonics.

This project will explore the use of novel semiconductors (such as van der Waals materials and perovskites) and/or advanced photonic architectures (such as metasurfaces and nanocavities). By achieving stronger nonlinearity, this project aims to demonstrate the viability of polaritonics for real-world applications in quantum computing, sensing, and all-optical information processing.

Desired background

A BSc in Physics, experience with novel semiconductors and photonics is desirable. The successful applicant would need to meet the Australian Government H1E standards and UNSW entry standards. Contact Eli Estrecho to discuss possibilities.
