    摘要: The invention provides an optical device which can lower the drive voltage which is used as one of the parameters for performance evaluation of the optical device. The optical device includes a substrate having first and second ridges, first and second grooves, a third groove, and first and second banks formed thereon, a Mach-Zehnder optical waveguide formed on the substrate, and an electrode set including first and second signal electrodes and a grounding electrode for controlling light which propagates in the optical wveguide. The grounding electrode extends to the first groove adjacent to the first bank and the second groove adjacent to the second bank. The optical device is applied, for example, to a transmission side apparatus for a long distance optical transmission system.

    摘要: A photodetector module including a support substrate having a main surface, an optical waveguide mounted on the support substrate and having an end face for emerging a light beam along a first optical path, and a photodetector mounted on the support substrate so that the light beam emerged from the end face of the optical waveguide is incident on the photodetector, the photodetector having a photodetecting portion responding to the light beam incident on the photodetector. The photodetector module further includes a first inclined surface formed on a substrate of the photodetector for refracting the light beam along the first optical path to a second optical path, and a second inclined surface for totally reflecting the light beam along the second optical path to a third optical path substantially perpendicular to the photodetecting portion.
