Document Type and Number:
Japanese Patent JP7004730
Kind Code:
B2
Abstract:
An isolator includes a first waveguide and a second waveguide on a substrate having a substrate surface, the first waveguide and the second waveguide located along the substrate surface and overlapping each other as viewed from the substrate. The first waveguide and the second waveguide each include a core and a clad. The core has a first surface facing the substrate surface, and a second surface opposite to the first surface. The clad contacts the first surface and the second surface of the core. The first waveguide has a first end and a second end, and has a port for input and output of electromagnetic waves at each of the first end and the second end. The core of the second waveguide includes a non-reciprocal member in at least one part of a cross section intersecting a direction in which the second waveguide extends.
