Abstract

Short distance optical interconnects and all-optical signal processing are gaining interest due to the steady increase of bandwidth demand in telecommunication and IT industries. The required level of opto-electronic integration demands small form factor device structures and new materials with tailored optical properties. If successful, lasers, light-emitting devices and switches based on hybrid organic-inorganic nanocomposites could become important due to their integration potential on arbitrary substrates. Furthermore, hybrid organic/inorganic materials are expected to exhibit large optical nonlinearities which could become essential in realizing fast all-optical switches.

Here, we will report on optimized photonic band-gap structures for lasing/switching applications as well as on the underlying electronic energy transfer processes in a model system constituting of an amorphous polyfluorene donor and an inorganic nanocrystal acceptor. Furthermore, we report on first results of plasmon-exciton interaction in order to tailor the optical properties of hybrid nanocomposites.
