AMO Seminar - Michael Crescimanno (Youngstown State University) "Non-linear Optics of Ultrastrongly Coupled Cavity Polaritons"

Experiments at 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 a pedagogic introduction to cavity polaritons,  we'll describe
quantum optics theory we use to quantitatively determine various non-linear optical effects including types of  low harmonic generation (SHG and THG)  in single and double cavity systems. Ultrastrongly coupled photon-matter systems such as these may be the foundation for technologies including low-power optical switching and computing.
