Abstract of the Disclosure A non-reciprocal optical device comprising a Faraday device made of a rare-earth iron garnet single crystal which can be in a magnetically saturated condition of Faraday rotation angle without an external magnetic field. Since a permanent magnet is omitted, the size of optical isolator or optical circulator can be more reduced than before. In addition, since the number of parts of the optical isolator or the optical circulator is reduced, the fabrication cost thereof can be reduced. 19
