EXTINCTION RATIO OF LIGHT OUTPUT BY POLARIZATION MAINTAINING FIBER

Extinction ratio of polarization-maintaining fiber length

The polarization extinction ratio (PER), also called polarization cross talk, in polarization-maintaining (PM) fiber-based devices is a key parameter. If you subject the fiber to high mechanical stress and small-diameter bends, then it is possible to disrupt the internal. PER is a parameter used to describe certain polarisation effects in optical fibres and components for optical fibre communication systems. The fiber cables made by Schäfter+Kirchhoff typically have a polarization extinction ≥ 200:1 (23 dB) or ≥ 400:1 (26 dB) for λ ≥ 780 nm (except for fibers end caps).

Polarization-maintaining fibers work by intentionally introducing a systematic linear in the fiber, so that there are two well defined polarization modes which propagate along the fiber with very distinct phase velocities. The beat length Lb of such a fiber (for a particular wavelength) is the distance (typically a few millimeters) over which the wave in one mode will experience an additional delay of one wavelength compared to the other polarization mode.
