Abstract
The invention is a spectrally selective optical coupler with a new geometry and a new principle of action. An optical coupler according to the invention includes an optical waveguide and an external resonator. In the waveguide, there is provided a deflector that is operative to deflect light of a predetermined wavelength into the external resonator. Coupling is enhanced by the deflected wavelength being resonant in the external resonator.
