Spike suppression in fiber amplifiers through nonlinear polarization rotation.
We report a pulse reshaping approach to suppress the harmful spike in fiber amplifiers. The approach is based on the nonlinear polarization rotation induced by the optical Kerr effect along the fiber. The feasibility and optimization of the pulse reshaping mechanism is analyzed theoretically and experimentally. An experiment is set up, and effective spike removal with low insertion loss of 0.5 dB is realized.
