ABSTRACT:
An integrated optic waveguide coupler having an interaction length throughout which two waveguides lie parallel and in contact with each other, in which the interaction length incorporates at least one straight section and, adjoining the straight section, there is provided at least one additional interaction length having a predetermined curvature. The curvature and the length of the interaction length together minimize wavelength sensitivity.
