The optical properties of hybrid organic-inorganic L3 nanocavities

We report the fabrication of L3 nanocavities defined into a free-standing silicon nitride (SiN) membrane coated with a thin (10 nm) film of fluorescent red-emitting conjugated polymer. We find that structures both with and without the conjugated polymer are characterized by a number of different confined optical modes with quality factors ranging between 450 and 1200. We characterize the polarization of the modes and discuss the enhancement of emission intensity from both the SiN and the polymer using spectral imaging. (C) 2010 Optical Society of America
