ABSTRACT:
An optical isolator comprises a polarizer, a Faraday rotator, an analyzer and a magnet for applying a magnetic field to the Faraday rotator wherein the polarizer is incorporated into a first metal cylinder to form a polarizer unit, the Faraday rotator is incorporated into a cylindrical magnet to form a Faraday rotator unit and the analyzer is incorporated into a second metal cylinder to form an analyzer unit, the polarizer, Faraday rotator and analyzer units being arranged within an outer cylinder and the first metal cylinder and the second metal cylinder being joined to the outer cylinder through an adhesive component. The optical isolator can easily be produced, the adhered and supported portion thereof is not peeled off and it has high reliability.
