For several millennia optical systems have been primarily based on one concept – reflection and refraction. While tremendous efforts have been made to miniaturise optical systems based on existing technologies, the lens-based approach to optics has proven a bottleneck in the system functionality. In recent years, with the progress in nanotechnology a new concept for manipulation of light in ultra-thin materials has emerged – the concept of meta-optics – “meta” meaning “beyond” in Greek.

This talk will introduce the recently established Australian Centre of Excellence for Transformative Meta-Optical Systems (TMOS). The Centre aims to transform the field optics as we perceive it today and create smart and miniaturized optical technologies with active 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 at the nanoscale. The talk will introduce Centre research program, which is a collective effort by a consortium of multiple Universities and Industries across the world.

Prof Dragomir Neshev is the Director of the Australian Research Council Centre of Excellence for Transformative Meta-Optical Systems (TMOS). He received the PhD 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 joined ANU in 2002. He is the recipient of a number of awards, including a Queen Elizabeth II Fellowship (ARC, 2010); an Australian Research Fellowship (ARC, 2004); and a Marie-Curie Individual Fellowship (European Commission, 2001). His activities span over several branches of optics, including periodic photonic structures, singular optics, plasmonics, and optical metasurfaces. He has published more than 250 journal articles, seven book chapters and an edited book.
