Opis:: We propose a new mechanism to achieve mode transformation. In a unidirectional air waveguide we place some metal slabs to form the unidirectional edge loop. Based on the effect of mode interference, the even mode or the odd mode can be completely canceled from their degenerated state through a precise adjustment of slab position, which leads to another mode to be released. By this mechanism, we have achieved continual transformations between even mode and odd mode.

Opis:: In the paper we present an implementation of resonance coupling between a unidirectional air waveguide and two cavities with one-way rotating state in a two-dimensional dielectric photonic crystal and a magneto-optical photonic crystal. We theoretically calculate the dispersion curves of the line defect waveguide and the dispersion curves of waveguide-cavity interaction, respectively. Numerical simulations show that, via waveguide-cavity coupling, a series of interesting resonance phenomena can be generated in the system. By modifying direction of the applied external magnetic field, storing and discharging of photonic energy can be realized. Our work may provide a practical and useful guidance for optical communications.
