Polarization mode splitting in monolithic polymer microcavities

We demonstrate the mode splitting of the resonant emission from a symmetric monolithic organic semiconductor microcavity. The device, realized by low-temperature reactive electron-beam evaporation and deposition of a conjugated polymer, exhibits a 100 meV polarization-induced splitting of the transmission and emission resonances for angles larger than 45 degrees. This opens the way for the realization of novel polarized-emitting optoelectronic devices based on plastic materials. (c) 2005 American Institute of Physics.
