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 13):
The optical circuit according to  claim 3 ,\n wherein, in the first optical 90\u00b0 hybrid, the first input port of the 2\u00d72 MMI element directly coupling with the second output port of the 2\u00d74 MMI element, the second input port of the 2\u00d72 MMI element indirectly coupling with the first output port of the 2\u00d74 MMI element through the phase shifter that shifts a phase of a beam output from the first output port of the 2\u00d74 MMI element by \u2212135\u00b0 with respect to another beam output from the second output port of the 2\u00d74 MMI element, the third and fourth output ports of the 2\u00d74 MMI element complimentarily generating the in-phase components of the first signal beam, the first and second output ports of the 2\u00d72 MMI element complementarily generating the quadrature components of the first signal beam, and wherein, in the second optical 90\u00b0 hybrid, the first input port of the 2\u00d72 MMI element directly coupling with the first output port of the 2\u00d74 MMI element, the second input port of the 2\u00d72 MMI element indirectly coupling with the second output port of the 2\u00d74 MMI element through the phase shifter that shifts a phase of a beam output from the second output port of the 2\u00d74 MMI element by \u221245\u00b0 with respect to another beam output from the first output port of the 2\u00d74 MIMI element, the third and fourth output ports of the 2\u00d74 MMI element complementarily generating the in-phase components of the second signal beam, the first and second output ports of the 2\u00d72 MMI element complementarily generating the quadrature components of the second signal beam.
