Name: Faraday Rotators and Mirrors - Pigtail Style
Brand: OZ Optics
Availability: InStock

Description

Faraday rotators change the polarization state of light traveling through it. The output polarization state is rotated by 45 degrees with respect to the input polarization. When combined with a mirror, the reflected light is rotated by another 45 degrees, resulting in a 90 degree rotation.

In addition, the polarization handedness is reversed by the mirror. This results in a reflected polarization that is orthogonal to the original polarization. This is useful when used in interferometers, because polarization changes through the fiber are cancelled out on the return journey.

Frequently Asked Questions

What is a Faraday rotator?

A Faraday rotator is a device that changes the polarization state of light traveling through it.

What is the output polarization state of light after passing through a Faraday rotator?

The output polarization state is rotated by 45 degrees with respect to the input polarization.

What happens when a Faraday rotator is combined with a mirror?

The reflected light is rotated by another 45 degrees, resulting in a 90 degree rotation. In addition, the polarization handedness is reversed by the mirror.

What are some applications of Faraday rotators and mirrors?

They can be used in fiber lasers, interferometers, sensors, amplifiers, circulators, and OCT systems.

What specifications should I consider when choosing a Faraday rotator or mirror?

You should consider the center wavelength, insertion loss, return loss, polarization extinction ratio, rotation angle, and rotation tolerance.
