摘要： PROBLEM TO BE SOLVED: To improve cross talk by having a structure that does not impair airtightness. SOLUTION: The optical hybrid integrated circuit includes a planar optical waveguide circuit for which an optical waveguide 121 is formed on a substrate and an optical module which is fixed on the planar optical waveguide circuit so that the light receiving face of an optical element is optically coupled to the optical waveguide 121. The optical hybrid integrated circuit is equipped with a mirror groove 102 which is formed on the end face 104 of the optical waveguide 121 deeper than the core thereof and an optical path conversion mirror 111 which is installed inside the mirror groove 102 and which couples the light signal emitted from the end face 104 of the optical waveguide 121 to the light receiving face of the optical element. The optical waveguide 121 is formed such that the core width in the end face 104 of the optical waveguide 121 is different from the core width in the circuit in the planar optical waveguide circuit, and that the flaring angle ψ of the beam in the full width at half maximum of light intensity of the optical signal emitted from the end face of the optical waveguide 121 becomes narrower at least in the substrate surface.

摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide circuit, having high controllability of the reflection angle and satisfactory yield of production. SOLUTION: The optical waveguide circuit comprises a first side face substantially orthogonal to an optical axis; a second side face facing the first side face substantially parallel to the same; and a third side face, arranged so as to form an internal angle with the second side face of 90° to 180°. Since the second-side face and the third-side face form the internal angle of 90° to 180°, a curable resin made to flow into a mirror groove can be prevented from swelling due to its surface tension on the third-side face. Accordingly, a reflecting part having a flat surface can be formed. Furthermore, the mirror groove can be prevented from being embedded by the curable resin. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of properly terminating the excessive power of light in a waveguide type device. SOLUTION: According to an embodiment, the waveguide type device includes a terminal structure filled with a light shielding material to terminate the light from the waveguide end. The terminal structure is formed by forming a groove on an optical waveguide by removing a clad and a core, and filling the groove with a material (light shielding material) which attenuates the intensity of the light. Thus, the light incident to the terminal structure is attenuated by the light shielding material and the effect to other optical devices is suppressed by becoming a cross talk component. Such a terminal structure suppresses not only the effect to the optical devices integrated in the same substrate, but also the effect to other optical devices directly connected to the substrate.
