    Abstract: A substrate is a substrate on which a first optical modulator and a second optical modulator are arranged in parallel along a width direction. A first prism moves, to a side opposite to the second optical modulator along the width direction of the substrate, an optical path of the first output light and the second output light that are obtained by light of the first wavelength being modulated by the first optical modulator. A second prism is arranged at a position away from the first prism along a longitudinal direction of the substrate and moves, to a side opposite to the first modulator along the width direction of the substrate, an optical path of the third output light and the fourth output light that are obtained by the light of the second wavelength being modulated by the second optical modulator.

    Abstract: An optical module includes a substrate on which an optical waveguide is formed, and an optical fiber assembly. The optical fiber assembly includes an optical fiber, a translucent member, and a mirror portion. The translucent member includes a joint surface joined to an end surface of the substrate at an end of the optical waveguide, and is attached to a distal end of the optical fiber. The mirror portion is formed on the translucent member, reflects light emitted from the distal end of the optical fiber in a direction different from a traveling direction of the light, and collects the reflected light into the end of the optical waveguide through the joint surface.

    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.
