Abstract:
An optical circuit that monolithically integrates a splitter, two optical 90° hybrids, and first to fourth waveguides on a unique substrate is disclosed. The splitter splits a local beam into first and second local beams each provided to the hybrids through the third and fourth waveguides, while, the signal beam including first and second signal beams each provided to the hybrids through the first and second waveguides without intersecting with the third and fourth waveguides. The hybrids extract in-phase components and quadrature phase components of the first and second signal beams with respect to the first and second local beams, respectively. The phase statuses of the quadrature components against the in-phase components are same in the two hybrids.

Claim (Index 2):
The optical circuit according to  claim 1 ,\n further comprising a polarization beam splitter and a polarization rotator each formed in the substrate, the polarization beam splitter splitting the signal beam into the first signal beam and the second signal beam, the polarization rotator rotating polarization of the second signal beam by 90\u00b0.
