Abstract: An optical device includes an optical waveguide that includes an incident waveguide, parallel waveguides along an electrode, and emission waveguides, formed on a substrate having an electro-optical effect, a first emission waveguide among the emission waveguides is set as an output waveguide of signal light, for output to an external destination and a second emission waveguide among the emission waveguides is set as a monitoring optical waveguide for the signal light; a photodetector that is disposed over the monitoring optical waveguide; and a groove formed on a portion of the substrate, where the photodetector of the monitoring optical waveguide is disposed. The monitoring optical waveguide has a width that, as compared with the width at a starting point side, is formed to increase as the monitoring optical waveguide approaches the groove.
