Elliptical polarization-maintaining fiber slow axis
The linearly polarized laser radiation is conventionally coupled into the slow axis because of its lower sensitivity to fiber bending. Beat length is a measure of the phase-velocity difference between. In fiber optics, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, maintains a linear polarization during propagation, exiting the fiber in a specific linear polarization state; there is. When splicing two PM fibers, their birefringent axes (usually the “slow” and “fast” axes) must be precisely aligned to avoid coupling light into the unwanted polarization state.
