Polarization-maintaining fibers work by intentionally introducing a systematic linear birefringence 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. Thus a length Lb /… WebPM Fiber Components Products Polarization-maintaining optical fiber normally transmits polarized light. It can ensure the direction of linear polarization and improve the coherent signal-to-noise ratio. Optical devices made with PM fiber have now already been widely used in aerospace, aviation, navigation and coherent communication.

WebDec 13, 2015 · In standard single-mode fiber, the polarization will tend to drift as the signal propagates (due to slight and varying birefringence of the glass, possibly stress-induced, coupling one polarization to the other). For short lenths (1 m or so) polarization is typically maintained fairly well.
