PROBLEM TO BE SOLVED: To easily manufacture an optical fiber with high accuracy. SOLUTION: An optical isolator is produced by inserting and adhering an optical fiber into the through hole of an outer supporting body, forming a groove crossing the optical fiber in the supporting body; preparing a composite body of an optical element composed of a polarizer and a Faraday rotator with a reinforcing member which surrounds the above optical element and fills the groove into the thickness to allow the composite body to fit in the groove, and then fitting and adhering the composite body in the groove. The reinforcing member is made of the same material as the outer supporting body or made of a permanent magnet. |
