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 7):
The optical reception device according to  claim 5 ,\n wherein the beam splitter includes:\n a first port to which the local light is input, \n a second port to which excitation light for exciting the rare earth ions is input, and \n a third port and a fourth port that respectively output the divided local light, and \n wherein the fourth optical waveguide includes a local light doped waveguide arranged between the beam splitter and the pair of optical hybrid circuits and doped with the rare earth ions.
