    • An optical integrated apparatus is used in an optical pickup apparatus which irradiates a light emitted by a light emitting device to an optical information record medium, on which record information is recorded, and receives a reflection light reflected from the optical information record medium. The optical integrated apparatus is provided with: a substrate; a light wave coupler for respectively generating a transmitted light and a guided light out of the reflection light; a light guide path for propagating the guided light; a first light receiving portion for receiving the transmitted light; and a second light receiving portion for receiving a radiant light which is generated out of the guided light and is directed toward the substrate due to a phase matching from the light guide path. The light wave coupler, the light guide path, the first light receiving portion and the second light receiving portion are laminated on the substrate. The first light receiving portion and the second light receiving portion are formed in a same layer on the substrate.
    • 一种光学集成装置用于将由发光装置发射的光照射到其上记录有记录信息的光学信息记录介质并接收从光学信息记录介质反射的反射光的光学拾取装置。 光学集成装置设置有:基板; 用于分别从反射光产生透射光和引导光的光波耦合器; 用于传播引导光的导光路径; 用于接收透射光的第一光接收部分; 以及第二光接收部分,用于接收从导光路径产生的辐射光,并且由于与导光路径的相位匹配而被引向基板。 光波耦合器,导光路径,第一光接收部分和第二光接收部分层叠在基板上。 第一光接收部分和第二光接收部分在基板上形成在同一层中。
