Title: Optical isolator
Inventor: FUKUSHIMA NOBUHIRO
IPC: G02B27/28
Filed: 1984-04-20
Abstract: PURPOSE:To enable continuous adjustment of isolation and to permit easy measurement thereof by providing a wave plate which can rotate around the optical axis orthogonally with the optical axis between a Faraday effect material and a polarizer or double refracting tapered plate. CONSTITUTION:The polarizing plane of the polarized light past a lambda/2 wave plate 5 rotates clockwise by 2theta angle and is shifted by 2theta angle from the plane of polarization of the polarizer 32 when the quick axis or slow axis of the plate 5 is shifted clockwise by the angle theta from the plane of polarization of the exit light from the Faraday effect material 4 and therefore 0.1% loss is generated when the angle theta is assumed to be 1 deg. at the time when said light passes through the polarizer 32. Such loss is negligible. On the other hand, the light from a light source 12, when made incident on the polarizer 32, passes through the polarizer 32 and the plane of deflection of the polarized light incident on the plate 5 rotates counterclockwise by 2theta angle thus making the isolation poor by 29dB from the infinity by the loss when the angle theta is 1 deg.. The continuous change of the isolation is thus made possible by changing continuously the angle theta.
