Non-linear Optics of Ultrastrongly Coupled Cavity Polaritons

Professor Mike Crescimanno

Department of Physics

Youngstown State University

Ohio, USA


Experiments at Case Western Reserve University (CWRU) have developed organic cavity polaritons that display world-record vacuum Rabi splittings of more than an eV. This ultrastrongly coupled polaritonic matter is a new regime for exploring non-linear optical effects. After an elementary introduction to the basic phenomena, we apply quantum optics theory to quantitatively determine various non-linear optical effects including types of  low harmonic generation (SHG and THG)  in single and double cavity polariton systems. Ultrastrongly coupled photon-matter systems such as these may be the foundation for technologies including low-power optical switching and computing.


Professor Mike Crescimanno received his bachelor degree in Physics from Princeton University in 1985. After then he went to Germany with a Fulbright/DAAD for a year. He had obtained his PhD in Physics from U.C. Berkeley in 1991 and worked as a postdoctoral researcher (1991-1994) in MIT. Professor Crescimanno taught Physics at Berea College, 1995-2000 and then joined Youngstown State University, Ohio where he has been working ever since. In his early days, his research was focused on string theory, low dimensional quantum field theory and some semi classical gravity. For the last decade he has been working more on cold atom Physics and quantum optics and optics. His wife, Mary, is a social worker (homeless education) and they have three kids.
