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 15):
The optical isolator according to  claim 2 , wherein\n the polarization converter is a quarter-wave plate.
