摘要：
A fiber optic system including an optical fiber (12), a coupling device (14), and a system for generating a pump signal (18). The optical fiber (12) has a birefringence which preserves polarization and has a first polarization mode which is substantially perpendicular to a second polarization mode. The coupling device couples an input signal (28) with an input wavelength into the optical fiber with the first polarization propagating mode. The system (18) for generating a pump signal (29) with a pump wavelength which is within a range of 50 nm to 300 nm less than the input wavelength and which has a first amount ofenough pump power to switch the input signal, but not enough to create higher order solitons. The pump signal (29) induces a nonlinear birefringence in the optical fiber which caused the input signal to switch polarization modes and propagate in the second polarization mode, and amplifies the input signal (28) propagating through the optical fiber.
