The optical module also includes a first connector electrically connected to the driver in the notch of the optical modulator. The optical module further includes a second connector provided on a surface of the notch of the optical modulator, the surface being opposed to the first connector. The second connector is electrically connected to the optical modulator. Furthermore, the optical module includes a coaxial pin that is connected to the first connector and the second connector and transmits the electric signal generated by the driver to the optical modulator.

Abstract: An optical device includes a substrate having an electrooptical effect, and including an optical waveguide that guides light and a reflection groove having a bottom face that reflects light output from the optical waveguide; and a light-receiving element positioned above the reflection groove and fixed to the substrate. The light output from the optical waveguide into the reflection groove is reflected by the bottom face of the reflection groove while traveling through a space inside the reflection groove and is incident to the light-receiving element.

Abstract: An optical module includes a driver that is provided on a board and generates an electrical signal according to a data signal, and an optical modulator that is connected to an optical fiber and provided on the board and that modulates light emitted from the optical fiber using the electrical signal generated by the driver. The optical module has a cut-out portion that is formed by cutting out part of its outer shape and that accommodates the driver so that the driver overlaps the optical fiber when viewed from a direction perpendicular to the board.

Abstract: An optical module includes a substrate on which an optical waveguide is provided; a housing that houses the substrate and includes a through path arranged on a side wall of the housing so as to extend in a direction that crosses the optical waveguide; a ferrule that houses an end portion of an optical fiber; and an optical path conversion element that is fixed on the ferrule, that is fixed on an end surface of the substrate on the end portion side of the optical waveguide, and that has a size smaller than a width of the substrate and a width of the ferrule along a longitudinal direction of the substrate. The end portion of the optical waveguide is arranged at a position close to the through path of the housing relative to a central portion in a width direction of the substrate.

Abstract: A first lens transmits a beam of light having a vertical cross-sectional diameter made closer to a horizontal cross-sectional diameter. The beam of light is emitted from an optical waveguide on a substrate and configured such that the vertical cross-sectional diameter which is the diameter of a vertical cross section along the direction of the thickness of the substrate is greater than the horizontal cross-sectional diameter which is the diameter of a horizontal cross section along the direction of the width of the substrate. A second lens is disposed at a position, at which the vertical cross-sectional diameter and the horizontal cross-sectional diameter coincide with each other, so as to focus the beam of light on the optical fiber. The position is closer to the optical fiber than the first lens along the direction of travel of the beam of light transmitted by the first lens.

Abstract: An optical device includes a thin film Lithium Niobate (LN) layer, a first optical waveguide, and a second optical waveguide. The thin film LN layer is an X-cut or a Y-cut LN layer. The first optical waveguide is an optical waveguide that is formed on the thin film LN layer along a direction that is substantially perpendicular to a Z direction of a crystal axis of the thin film LN layer. The second optical waveguide is an optical waveguide that is routed and connected to the first optical waveguide. At least a part of a core of the first optical waveguide is made thicker than a core of the second optical waveguide.
