Feedback in optical microcavity arrays — •Rebecca Cizek, Jakob Kreismann, and Martina Hentschel — TU Ilmenau, Ilmenau, Germany

Arrays of coupled optical microcavities are a rich and interesting model system with a big potential for applications [1]. Their functionality relies on the mutual coupling between the individual mircoresonators. Here, we study in detail how the coupling between two asymmetric optical microresonators depends on their geometric properties like distance, orientation, cavity size and resonance detuning based on numerical wave simulations using the FDTD package MEEP. In particular, we characterize the robustness of coupling and feedback in detuned cavities that is of special importance for applications where detuning can result from fabrication imperfections.
