Harnessing optical metasurfaces for reconfigurable optoelectronic devices
Grant number: DP180104141 | Funding period: 2018 - 2020
This project aims to demonstrate ultra-thin optical components known as metasurfaces, to demonstrate a new class of reconfigurable optoelectronic devices. This project expects to generate new knowledge in optics and photonics, a field whose impact upon modern society ranges from telecommunications to computing, green energy technologies, the arts, healthcare, and basic science. Expected outcomes of this project will be elucidation of the fundamentals underpinning optical metasurfaces. Such devices will permit optical systems with drastically smaller footprints, contributing to continued progress of the field of optics and photonics, and its ensuing benefits to society.
