Isolator and method of magnetization for isolator

Abstract

An isolator 10 includes an optical chip 11, a first substrate 12, a first magnetic member 13, and a second magnetic member 14. The optical chip 11 includes a waveguide 16. The waveguide 16 is configured to propagate an electromagnetic wave in an extending direction of the waveguide 16. The optical chip 11 is mounted on the first substrate 12. The first magnetic member 13 is fixed at one side of the waveguide 16 in a first direction. The first direction is perpendicular to the extending direction and is parallel to a main surface of the first substrate 12. The first magnetic member 13 includes at least one magnetic body. The second magnetic member 14 is fixed at the other side of the waveguide 16 in the first direction. The second magnetic member 14 includes at least one magnetic body.
