Abstract:
An optical reception device includes an optical waveguide substrate that includes a polarization beam splitter that divides reception light into an X polarization component and a Y polarization component orthogonal to the X polarization component, a beam splitter that divides local light, a pair of optical hybrid circuits that causes each of the X polarization component and the Y polarization component to interfere with the divided local light, a first optical waveguide through which the reception light passes, a second optical waveguide through which the X polarization component passes, a third optical waveguide through which the Y polarization component passes, and a fourth optical waveguide through which the local light passes, wherein at least one of the first to fourth optical waveguides is doped with rare earth ions for amplifying light having a predetermined frequency when excitation light is introduced.

Claim (Index 4):
The optical reception device according to  claim 2 ,\n wherein the optical waveguide substrate includes a second optical multiplexer that multiplexes excitation light for exciting the rare earth ions and the local light and outputs the multiplexed light to the beam splitter, and wherein the fourth optical waveguide includes a second doped waveguide arranged between the second optical multiplexer and the beam splitter and doped with the rare earth ions.
