Self-switching of optical pulses in gain-distributed nonlinear amplifying fibre loop mirror

摘要

Self-switching of optical pulses in a gain-distributed nonlinear amplifying fibre loop mirror is investigated numerically in the soliton regime. Results show that, compared with the conventional nonlinear fibre loop mirror with a lumped gain inside or outside the loop, the present device can produce higher-quality pulses and permits more efficient pulse compression.
