Повышение пространственного перекрытия резонансных мод фотоннокристаллического нанорезонатора

New photonic crystal nanocavity geometries are suggested and numerically studied. Such nanocavities have an enhanced spatial modal overlap. It is also possible to independently tune the cavity resonance modes frequencies. The case of degenerate resonance modes is studied. Nanocavities with circle holes and slots are studied. I t is demonstrated that the nanocavities with slots allow to enhance spatial overlap of orthogonally polarized resonance modes. It is shown that closed slots can be used to increase the quality factor of nanocavities.
