The integration of optical components at the chip level demands for novel device concepts and material systems. In this talk we present our work towards two important functions: lasing and switching. We report on a surface-emitting mixed-order photonic crystal laser with an organic gain material. This photonic structure enhances the optical confinement and the mode coupling and enables lasing thresholds as low as 40 pJ optical pump energy with 15um x 15um active device area. Hybrid organic/inorganic materials are expected to exhibit large optical nonlinearities which could become essential in realizing fast all-optical switches. We study the underlying fundamental electronic energy transfer processes in an amorphous polyfluorene donor CdSe/ZnS core-shell nanocrystal acceptor system.
