Abstract :
We have developed a compact in-line polarimeter for monitoring the polarization of light in active fiber. It consists of two parts: a half-mirror inserted into a trench cut at a slant across the fiber so that it reflects a portion of the optical beam and the combination of a magnetized Faraday rotator plate sandwiched between mirrors and a four-channel detector.
