| Abstract | Recently, organic based microcavities became a focal point in the boundary photonic research due to the special features of the organic active molecules whose properties may be easily modulated. By using the thermal evaporation we realized double and triple coupled-microcavity structures containing one or more active layers of light emitting organic molecules. The resonators are tuned at the same wavelength and coupled by low reflectivity mirrors. In particular we grew an asymmetric double system with only one active organic layer embedded in one microcavity. The reflectivity measurements show that the coupling between the two resonator results in a splitting of the optical modes. The photoluminescence spectra display a double wavelength emission. The comparison of the diagonalized effective Hamiltonian with the observed resonances further confirms the strong coupling between the two cavities. A quantum statistical approach for interacting quantum systems in the strong coupling regime reproduces with very good agreement the experimental results. The triple structure has been designed to improve the coupling among the resonators. The device shows three emission peaks at different wavelength and represents a very interesting start up to realize white organic based LEDs and ultrafast optical amplifiers. |
