光调制器
摘要：
本发明提供一种光调制器，在多个调制部的每一个调制部具有受光元件的光调制器中缩短了芯片宽度。光调制器具备：具有电光效应的基板(1)；形成在该基板(1)上的光波导(2)；分别对在光波导(2)中传播的光波进行调制的调制部(M)；检测在光波导(2)中传播的光波的受光元件(4)。作为调制部(M)，具有分别对使输入光分支后的各光波进行调制的第一调制部(M(#1))及第二调制部(M(#2))。作为受光元件(4)，具有针对调制部(M(#1))的受光元件(4(#1))和针对调制部(M(#2))的受光元件(4(#2))。受光元件(4(#1))和受光元件(4(#2))将光传播方向的位置错开一个受光元件以上地配置。
摘要（英）：

An optical modulator includes a substrate having an electro-optic effect, an optical waveguide formed on the substrate, a modulation part which modulates light waves propagating through the optical waveguide, and a light receiving element which detects the light waves propagating through the optical waveguide. As the modulation part, a first modulation part and a second modulation part, which respectively modulate light waves into which input light branches, are provided. As the light receiving element, a light receiving element for the first modulation part and a light receiving element for the second modulation part are provided. The light receiving elements are disposed such that their positions in a light propagation direction are shifted from each other by an amount corresponding to one light receiving element, or more.
