Abstract:
An apparatus includes a first coupler configured to input input light through an input waveguide and branch the input light into first and second branch waveguides; a second coupler configured to combine the first and second branch waveguides and to output the output light through an output waveguide; a phase adjuster having a birefringent property, provided to the second branch waveguide; and a polarization converter having a birefringent property, provided to the output waveguide and configured to, when reflected light corresponding to the output light is input to the output waveguide, convert a polarization state of the reflected light such that a first part of the reflected light for traveling through the first path and a second part of the reflected light for traveling through the second path are in antiphase at the input waveguide.

Claim (Index 6):
The optical isolator according to  claim 2 , wherein\n the optical waveguide further includes a first auxiliary waveguide adjacent to the input waveguide, the first coupler connects the input waveguide, the first auxiliary waveguide, and the first and second branch waveguides, and the polarization converter converts the polarization state of the reflected light such that the light for traveling through the first path and the light for traveling through the second path are in antiphase at the input waveguide and are in phase at the first auxiliary waveguide.
