An optical circuit device comprises a substrate (10) of a III-V group compound semiconductor, and a magnetic semiconductor layer (14) having a chalcopyrite type crystal structure. A magnetic semiconductor having the chalcopyrite type crystal structure is a material which can provide the Faraday effect, and, therefore, can be used to form a Faraday rotation element (22). Furthermore, a magnetic semiconductor having the chalcopyrite type crystal structure that is lattice-matched with the substrate (10), has fewer crystal defects, which can reduce light loss from the Faraday rotation element (22). A magnetic semiconductor of the chalcopyrite type crystal structure can provide a large Verdet's constant, which makes it possible to reduce a length of the Faraday rotation element (22) and, therefore, to micronize such an optical circuit device.
