Method and apparatus for reducing polarization dependent gain in Raman amplification |
摘要 |
A method and apparatus for providing broad band Raman amplification with reduced dependence on polarization state and wavelength. Pump beams of adjacent wavelength are perpendicularly polarized to each other. Further, the wavelength spacing between adjacent pump beams is chosen for the given fiber wavelength spectrum and distance between repeater stations such that adjacent pump beams experience the same polarization state evolution as they travel through the fiber.
