Abstract
We design a new kind of optical storage composed of a ring resonator that is based on
both the one-way property of the edge modes of magneto-optical photonic crystals and the coupling
effect of cavities. The ring resonator can be served as an optical storage through a close field
circulation. Through another edge waveguide and coupling cavity, the electromagnetic signals can
be either written into the storage or be taken out from it.
