Abstract
An optical integrated circuit includes a substrate including a substrate surface, a first waveguide and a second waveguide configured to allow electromagnetic waves to propagate along the substrate surface, and a non-reciprocal member disposed on a side of the first waveguide and the second waveguide remote from the substrate surface. At least part of the non-reciprocal member is disposed in a range of a mode field diameter of TM mode electromagnetic waves in the first waveguide. The non-reciprocal member is not disposed in a range of a mode field diameter of TM mode electromagnetic waves in the second waveguide.
