Abstract: An absorption modulator is provided. The absorption modulator includes a substrate, an insulation layer disposed on the substrate, and a waveguide having a P-I-N diode structure on the insulation layer. Absorptance of an intrinsic region in the P-I-N diode structure is varied when modulating light inputted to the waveguide. The absorption modulator obtains the improved characteristics, such as high speed, low power consumption, and small size, because it greatly reduces the cross-sectional area of the P-I-N diode structure.

Abstract: In an optical waveguide device, in a cross direction intersecting an extension direction of waveguide sections, one or more bridge portions of a ground electrode closer to a center of stress distribution of a stress due to a support member, and one or more bridge portions of a ground electrode farther from the center of stress distribution are formed with different shapes. The structure of the ground electrodes is devised so that a stress negating the difference in stress characteristics between the plurality of waveguide sections, generated by the stress applied from the support member to a substrate, is applied from the ground electrode to the substrate.
