Abstract

See full text

An optical isolator includes: an optical isolator chip in which a first polarizer, a Faraday rotator made of a ferromagnet, and a second polarizer are bonded and fixed in this order; and a magnet for applying a magnetic field to the optical isolator chip. A light-entering end surface or a light-exiting end surface of the optical isolator chip is bonded and fixed to a component. On an optical axis of the optical isolator, a center of a magnetic flux formed by the magnet is positioned closer to the end surface side bonded and fixed to the component than a central position of the Faraday rotator on the optical axis. The optical isolator has high bonding reliability to the component.
