Cross-coupled composite-cavity organic microresonators
- Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) and Institute for Applied Physics, Technische Universität Dresden, 01062 Dresden (Germany)
We report on cross-coupled composite-cavity microresonators consisting of a vertical cavity and a second-order distributed feedback structure which employ the same organic active medium and support surface-normal and in-plane emission at the same time. The optical coupling is due to a first-order light diffraction on a second-order Bragg grating and, in the degenerate case, can be as efficient as the coupling observed in more classical cascade coupled cavities. When the system is non-degenerate, the diffraction efficiency is suppressed because of sub-coherence-length dimensions of the composite-cavity and both resonators tend to operate as independent structures without experiencing substantial losses due to diffraction on the distributed-feedback grating.
