Abstract
While the gain bandwidth of Er-doped fiber amplifiers is in the range of 60 fs, most fiber figure eight lasers produce approximately 200 fs pulses. We show that higher order terms, including third-order dispersion, self-frequency shifting, and self-steepening, severely limit the efficiency and pulse quality for ultra-short pulses propagating in the nonlinear amplifying loop mirror, which acts as a gain medium and a modelocker in these lasers. We also compare the nonlinear optical loop mirror used as an ultra-fast all-optical switch at various control pulse power levels.
