A two-channel optical fiber fused coupler comprising two optical fibers, each with a core and cladding, fused together at a narrow tapered waist. The first channel is at a wavelength of .lambda.1 and the second channel is at a wavelength of .lambda.2 where .lambda.2 is longer than .lambda.1. The coupler is fabricated to have a characteristic wavelength .lambda.0 such that for wavelengths .lambda.2 longer than .lambda.0 coupling occurs and for wavelengths .lambda.1 shorter that .lambda.0 the light at .lambda.1 is core guided throughout the coupler and thus does not couple across.
