摘要：The channel add/drop filter includes first and second 2D photonic crystals, andthe first 2D photonic crystal includes a first waveguide and a first cavity, with the firstcavity acting to take in light of a specific wavelength from the first waveguide and radiateit outside the first photonic crystal, and the second 2D photonic crystal includes a secondwaveguide with substantially the same characteristics as the first waveguide and a secondcavity with substantially the same characteristics as the first cavity. The first and secondwaveguides are optically connected so that when the principal plane of the first 2Dphotonic crystal and the electric-field vector of the light within the first waveguide forman arbitrary angle a, the principal plane of the second 2D photonic crystal and theelectric-field vector of the light within the second waveguide form an angle of alpha + ( pi/2).
