Optimizing launch points for dispersion-managed solitons

摘要

There is described an asymptotic theory for predicting the evolution of dispersion-managed solitons with loss and gain. Optimal launch points for dispersion-managed solitons where the pulses do not need to be prechirped can be readily located. Numerical results demonstrate that launching the pulses with proper phase chirp and power significantly reduces pulse amplitude and width oscillations and the amount of dispersive radiation, without regard to wavelength.
