Abstract

PURPOSE:To assure the stable joining for the purpose of optical joining extremely accurately in terminal parts by depositing a magnetic metallic layer on the outside circumferential end parts of stationary and movable optical fibers, forming the opposite placing parts of both fibers as V-shaped grooves, and disposing electromagnets in said grooves. CONSTITUTION:Stationary optical fibers 46-49 are disposed at the intermediate of the V-shaped grooves 42-45 formed to a hollow cylindrical holder 40, and a movable optical fiber 51 is fixed and disposed in opposition to the end part of the stationary fiber 46 in a curved state in a manner as to make optical connection by placing its end part on the V-groove 42. Electromagnets 54-57 are buried from the outside circumference of the holder 40 toward the V grooves 42-45, and the magnetic pole magnetic bodies 58-61 thereof are secured across the stationary and movable optical fibers at close distances from the V grooves or in connection to the fibers 46-49. These magnetic poles 58-61 are all formed of permanent magnets or magnetic materials holding suitable residual magnetic force. Thereby, the extremely stable joining in the terminal parts is accomplished.
