摘要： Optical isolator comprises a ferrule having a through-hole in which an optical fiber is inserted and a groove formed in the ferrule with the optical fiber inserted in the through-hole; and a composite assembly consisting of an optical isolator element composed of a Faraday rotator and a pair of polarizers fixed on opposite surfaces of the Faraday rotator in such manner that the angle between the directions of polarization of the polarizers is at about 45° and a structure reinforcing member having a thickness of filling the groove and surrounding the optical element, said composite assembly being inserted in the groove as a unit. The reinforcing member may be made of the same material as the outer support or formed by a magnet for applying a magnetic field to the Faraday rotator. The isolator element, the magnet and the outer support may have respective reference sides or planes so that the plane of polarization of the incident side of the isolator element is easily determined with respect an outer base or support. Also, the groove portion of the support is mechanically strengthened by the magnet surrounding the optical element.

摘要： An optical isolator having an optical element, comprised of an incoming side polarizer, a Faraday rotator, and an outgoing side polarizer superposed in the order of mention in the direction of an optical path, is embedded in the optical path of an optical fiber or optical waveguide having a light axis. The isolator has a slot extending across the light axis in a direction slanted with respect to the light axis. The optical element is inserted in the slot and the spaces between the optical element and the incoming and outgoing sides of the slot are filled with an optical adhesive portion. At least one of the interfaces is inclined at an angle reversely from the plane normal to the light axis as viewed from the slanted incoming side of the slot.
