Free Space Faraday Rotator and Isolator

Faraday Rotator is an optical device based on the Faraday effect. The linearly polarized light input can be rotated to specified angles, and the direction is only related to the internal magnetic field. Optical Isolator is made of three parts, an input polarizer, a Faraday rotator, and an output polarizer. It is an optical component which allows the transmission of light in only one direction. It is widely used for amplified lasers, mode-locked lasers and optical test instrumentation.
