Dipolarized Source for High Power Operation of an Optical Modulator.

Abstract

This patent application discloses a method and apparatus for counteracting polarization fading and stimulated Brillouin scattering in long runs of non-polarization maintaining optical fiber. A linearly polarized optical signal is depolarized by phase modulating the signal at a frequency significantly above the fiber's Brillouin scattering linewidth V sub b prior to launch into the long run of fiber.
