Nettet20. apr. 2024 · The two axes in a PM fiber are sometimes called the “slow axis” and the “fast axis,” because they have different indices of refraction. This means that light waves in the two polarization modes will have different phase velocities. Beat length is a measure of the phase-velocity difference between the two polarization modes.
