摘要： An optical modulator is provided which can compensate for a bias shift between an output light and a monitoring light of the optical modulator and which has a configuration capable of being reduced in size with a simple structure. The optical modulator comprises a substrate that has an electro-optical effect, an optical waveguide that includes a Mach-Zehnder type optical waveguide formed in the substrate, a modulation electrode that modulates light waves propagating in the optical waveguide, an optical fiber that guides an output light from the optical waveguide, light collecting means for collecting two radiated lights from the Mach-Zehnder type optical waveguide toward a single optical receiving element, and light intensity ratio adjusting means for adjusting a light intensity ratio of the two radiated lights received by the optical receiving element.
