Abstract
In an optical modulator, a light-receiving element (3a) that receives a light wave modulated in an optical modulation section (Ma) and a light-receiving element (3b) that receives a light wave modulated in an optical modulation section (Mb) are provided in a substrate. In addition, at least a part of an electrical line (4a) that guides a light-receiving signal output from the light-receiving element (3a) to an outer side of the substrate, and at least apart of an electrical line (4b) that guides a light-receiving signal form the light-receiving element (3b) to an outer side of the substrate are formed in the substrate. In addition, crosstalk suppression means (5), which suppress crosstalk between the electrical line (4a) and the electrical line (4b), is provided between the part of the electrical line (4a) and the part of the electrical line (4b) which are formed in the substrate.
