Abstract

PURPOSE:To obtain a high quenching ratio by boring a storage hole in a cylindrical case at a prescribed angle from the center axis, and putting and fixing a Faraday rotary disk and deflector plates in the storage hole and thus constituting an optical isolator. CONSTITUTION:The storage hole 4a which slants at the prescribed angle from the center axis is bored in the cylindrical case 4. The Faraday rotary disk 2 and a couple of deflector plates 1 and 1 on both sides of the Faraday rotary disk 2 are combined and stored fixedly in the storage hole 4a to constitute the optical isolator 3. The tilt angle is about 5-7 deg.. Further, a mark 9 is formed on the surface of the cylindrical case 4, which is rotated with the mark 9 as a guide through a hole 5a in the side wall of a pyramidal member 5 for holding the cylindrical case 4, thereby adjusting the optical isolator 3 finely. Thus, the optical isolator is stored and fixed in the cylindrical case slantingly, so reflected light is prevented from being generated to increase the quenching ratio and the optical isolator is easily adjusted.
