Faraday Effect in Long Telecom Fibers with Randomly Varying Birefringence
M. Brodsky, A. A. Sirenko, A. Zavriy, Alexei S. Trifonov · 2006
We measure relative propagation delay between two orthogonally polarized pulses in long fibers in the presence of a weak axial magnetic field (~50μT). We find that the fiber birefringence modifies the Faraday polarization eigenstates, which became noncircular and wander in time.
