Abstract

See full text

An isolator comprises a substrate having a substrate surface; and first and second waveguides that are positioned at least partially side by side along the substrate surface. The first waveguide includes a first core, the second waveguide includes a second core, and the first and second cores are surrounded by a dielectric. The first waveguide includes first and second ends, and includes a port through which an electromagnetic wave is input and output at each of the first and second ends. The second waveguide includes a first portion extending along the first waveguide and a second portion that is not included in the first portion. The second waveguide includes a nonreciprocal member that is in contact with at least a part of the second core of the first portion, and the nonreciprocal member is in contact with at least a part of the second core of the second portion.
