-1- Abstract: A waveguide type optical multiplexer/demulti- plexer has a directional coupler made of a three-layer structure wherein core waveguides (refractive index nc: nc > nb) and a cladding (refractive index nr: nr < nc) are successively stacked on a low refractive index layer (refractive index nb). The device is provided with a thin film heater in or on the cladding, and a voltage is applied across the heater. The arrangement permits variation of the temperature dependent refractive indices and hence provides for connection of the undesirable center wavelength shift that can occur in manufacture or use.
