ABSTRACT:
An interference waveguide device made of a material with a positive derivative of refractive index over temperature may be combined with a compensating waveguide device. The compensating waveguide device may be made of a material with opposite and larger derivative of refractive index. The outputs of the compensating device may be selectively coupled to inputs of the interference device to provide an athermal interference waveguide device.
