Abstract
An isolator includes a substrate, a waveguide and an electronic circuit disposed above the substrate, and a non-reciprocal member disposed above the waveguide and the electronic circuit. The non-reciprocal member includes a first portion in contact with the waveguide and a second portion disposed within a predetermined range from the electronic circuit. Non-reciprocity in the second portion is weaker than non-reciprocity in the first portion.
