Abstract:
We report on the control of spontaneous emission in flexible polymer 1D photonic crystal cavities fabricated by spin coating having a layer of poly(9,9-dioctylfluorenyl-2,7-diyl-co-1,4-
benzo-(2,10-3)-thiadiazole) (F8BT) as an active material. The optical properties of these full-polymer photonic crystals are systematically investigated by means of polarized angular-resolved transmittance and photoluminescence spectral measurements. We demonstrate strong directional emission
enhancement when the emitter is located in the defect layer and resonantly coupled to the microcavity mode. The experimental results can be successfully reproduced with different theoretical optical models.
