Applied Physics Seminar

Transformative Meta-Optical Systems
Dragomir N. Neshev, Professor, Physics, Australian National University,

Abstract:

In this talk, I will introduce the recently established Australian Centre of Excellence for Transformative Meta-Optical Systems (TMOS). The Centre aims to create smart and miniaturized optical technologies with functionalities not possible to date. This will be achieved by the research and development of nanostructured materials that can actively generate, manipulate and detect light. The Centre is a consortium of multiple Universities and Industries across the world, with Caltech being a major partner.

As a part of the Centre's research program, I will further present some examples of our current research activities, including (i) manipulation of light emission from 2D semiconductors by photonics nanostructures; (ii) generation of bi-photon quantum states by parametric down-conversion in nanoscale resonators; and (iii) image switching in tunable dielectric metasurfaces.

About the Speaker:

Dragomir Neshev is a Professor in Physics at the Australian National University (ANU) and the Director of the Australian Research Council Centre of Excellence for Transformative Meta-Optical Systems (TMOS). He received the Ph.D. degree from Sofia University, Bulgaria in 1999. Since then he has worked in the field of optics at several research centres around the world and joint the ANU in 2002. He is the recipient of a number of awards, including a Queen Elizabeth II Fellowship (2010); an Australian Research Fellowship (2004) and a Marie-Curie Individual Fellowship (2001). His activities span over several branches of optics, including periodic photonic structures, singular optics, plasmonics, and optical metasurfaces.
