Abstract: A polarization coupling device includes a polarization combining element. The polarization combining element includes a polarization rotating unit that rotates a polarization direction of a first polarized wave incident on the polarization combining element, and a polarization combining unit that combines the first polarized wave with the polarization direction rotated by the polarization rotating unit and a second polarized wave incident on the polarization combining element with each other, and the polarization rotating unit and the polarization combining unit are integrated with each other. Due to this configuration, the polarization coupling device has an effect where downscaling of the device can be advanced.

Abstract: A housing accommodates an optical waveguide substrate, plural signal light receiving elements, and a signal-light-level monitoring light receiving element. Signal light and locally oscillated light are input into optical waveguides in the optical waveguide substrate from a first end face of the optical waveguide substrate. The plural signal light receiving elements are disposed aligned on a side of a second end face opposite to a side of the first end face of the optical waveguide substrate. The signal-light-level monitoring light receiving element is disposed on a side of a third end face or a fourth end face between the first end face and the second end face of the optical waveguide substrate and at a position closer to the first end face than to the second end face.
