Abstract
An isolator includes a substrate, a waveguide, an insulating layer, and a non-reciprocity member. The insulating layer includes a recess. The recess overlaps at least part of the waveguide. The non-reciprocity member is positioned in the recess. The waveguide includes a first waveguide and a second waveguide. The recess includes a first recess and a second recess. The non-reciprocity member includes a first non-reciprocity member positioned in the first recess and a second non-reciprocity member positioned in the second recess. A propagation direction of the electromagnetic wave in a portion of the first waveguide, the portion overlapping the first non-reciprocity member, and a propagation direction of the electromagnetic wave in a portion of the second waveguide, the portion overlapping the second non-reciprocity member, are different from each other.
