Abstract
In recent years, significant interest has emerged in the inverse design of artificial layered heterostructures for photonic applications. Specifically, the unique optical properties of near-zero permittivity (ENZ) metamaterials have enabled the exploration of novel physical effects and mechanisms. In this presentation, I will delve into how thin film photonics harnesses the potential of Fano resonances and extreme optomechanics. By layering metal-dielectric thin films, we can create a distinct type of optical coating that exhibits photonic Fano resonance, referred to as a Fanoresonant optical coating (FROC). We extend the concept of coupled mechanical oscillators to thin film nanocavities, shedding light on semi-transparent FROCs that can both transmit and reflect the same color, akin to a beam splitter filter. This remarkable property is beyond the capabilities of conventional optical coatings. In the latter part of my presentation, I will discuss recent theoretical and experimental efforts aimed at exploring optomechanics based on epsilon-near-zero materials.
Biography
Giuseppe Strangi (http://physics.case.edu/faculty/giuseppe-strangi/) is a Professor of Physics and an Ohio Research Scholar in Advanced Materials Surfaces at Case Western Reserve University, where he also leads the Nanoplasm Labs (https://nanoplasmlab.com/). In addition, he serves as a Senior Scientist at the National Research Council (CNR) in Italy. Strangi is the President of the Scientific Committee for the "Con il Cuore" Foundation, which supports cancer research across Europe, and he is the General Chair of the NANOPLASM International Conference, dedicated to exploring new frontiers in plasmonics and nanophotonics. His research spans condensed matter physics, nanophotonics, plasmonics, and cancer nanotechnology. Strangi is a Fellow of Optica (formerly the Optical Society of America), as well as the Institute for the Science of Origins and the Case Comprehensive Cancer Center at CWRU.
