Polarizing optical isolator is a device specially designed for use in optical systems. It can effectively isolate reverse propagating light and ensure that light propagates in only one direction. Its working principle is based on the Faraday effect, which is to change the polarization state of light through an external magnetic field, thereby achieving unidirectional light propagation. This device usually consists of a polarization rotator and a Faraday rotation material. When light enters with a specific polarization direction, the isolator allows the light to pass; when reverse light enters, the reverse light is blocked due to the change in polarization direction.
