| Abstract: | We report the first laterally coupled hexagonal micro-pillar resonator add-drop filters in silicon nitride. Our experiment reveals waveguide-coupled resonances of 6-bounce ray orbits in the hexagonal microcavity. By tuning the sub-micrometer waveguide width, we demonstrate simultaneous optimization of the coupling efficiency and the resonance Q value. We attribute the optimum waveguide width to the near k-vector matching between the input and output-coupled waveguide fundamental mode and the cavity 6-bounce modes that are coherently coupled along the resonator flat sidewalls. |
