Abstract : The patent describes a passive frequency-selective optical coupler comprising first and second dielectric waveguides disposed in proximate (preferably parallel) spatial disposition relative to each other. A phase propagation constant at a known frequency is common to guided modes of both dielectric waveguides while the phase propagation constants of the guided modes at all other frequencies are different. Signal transmission in the form of light energy may therefore be multiplexed for transmission along one of the dielectric waveguides, with selective coupling of only the known predetermined frequency to the other dielectric waveguide at that portion where the waveguides are arranged in proximate spatial disposition relative to each other.
