Title: Optical isolator
Inventor: ONODA YOSHITO
IPC: G02B27/28
Filed: 1985-09-27
Abstract: PURPOSE:To compensate variance in the Faraday rotational angle of a Faraday rotator and to obtain invariably stable and high isolation characteristics by allowing either of an incidence polarizing prism and a projection polarizing prism to rotate to the other. CONSTITUTION:The 1st holder H1 is allowed to rotate around the center axis of its boss H1a to the 2nd holder H2. The incidence polarizing prism P1 is rotated to the Faraday rotator FR and projection polarizing prism P2 in a plane perpendicular to the applied magnetic field direction of a magnet M (i.e. plane perpendicular to the center axis of rotation of the holder H1) by rotating the 1st holder H1. Then, the angle of deviation between the optical axes of the incidence polarizing prism P1 and projection polarizing prism P2 is adjusted to coincide with the angle of Faraday rotation of the Faraday rotator FR. Consequently, even if the angle of Faraday rotation of the Faraday rotator FR has variance, it is compensated by the rotation of the projection polarizing prism P1 to obtain the invariably stable and high isolation characteristics.
