Description

The Polarization Filter is a compact high performance component that splits input signals into two separate orthogonal Polarizations on two different output fibers. The most common application is to splits the light in two separate output fibers. The typical configuration uses Pm/SM fibers for the input and two PM fibers for the output. It has application in Fiber sensors and Laser interoferometers. The devices are based on Bulk optics.
