Aolarization Maintaining Isolator

A polarization maintaining isolator is a device that allows light to pass through in one direction

while blocking it in the opposite direction,while also maintaining the polarization state of the light. 

It is specifically designed to preserve the polarization of light as it propagates through the isolator.

In a polarization maintaining isolator, the input and output ports are designed to align with the polarization axis of the light. 

This ensures that the light passing through the isolator maintains its polarization state.

Any light that is not aligned with the polarization axis will be blocked or attenuated.

Polarization maintaining isolators are commonly used in applications where preserving the polarization state of the light is crucial, 

such as in fiber optic communication systems, fiber lasers, and other polarization-sensitive optical systems. 

They help to minimize the impact of polarization fluctuations and maintain the integrity of the transmitted signal.

It's worth noting that while a polarization maintaining isolator can maintain the polarization state of light,

it is not necessarily polarization insensitive. Polarization insensitive isolators, as mentioned earlier, 

allow light to pass through regardless of its polarization state,

while a polarization maintaining isolator preserves the polarization state of the light.
