What is  magneto-optical switch?

Magneto-optical switch is a device that uses the Faraday magneto-optical effect to switch optical signals. Specifically, when linearly polarized light propagates in a magnetic medium, if it is affected by an external magnetic field, its polarization plane will rotate. This phenomenon is called the magneto-optical effect. The magneto-optical switch rotates the polarization plane of the incident light by changing the external magnetic field, thereby achieving the purpose of switching the optical path.

Advantages of magneto-optical switches include:

No moving parts, so low power consumption and stable and reliable;
The switching speed is fast and the response time is tens of microseconds;
The process is relatively simple.
However, the inconvenience of magneto-optical switches is that they are not easy to integrate. This kind of switch is widely used in situations where high-speed optical signal switching is required, such as key nodes in optical communications and optical networks.
