Exciton Polaritons in Optical Microcavities and Their Prospects for Electrically Pumped Organic Lasers

Summary form only given. We discuss the study of strongly coupled states based on optically pumped molecular organic thin films deposited in vacuum. These states have applications to nonlinear optics, and more speculatively, to coherent light emission. Our studies extend to several different molecular organic species, as well as coupled Wannier-Frenkel exciton states in hybrid organic/inorganic quantum well semiconductor systems. The prospects of employing these fundamental excitations for nonlinear optical devices are discussed.
