Dispersion compensating nonlinear polarization amplifiers

摘要

A broadband nonlinear polarization amplifier includes an input port for inputting an optical signal having a wavelength lambda. A distributed gain medium receives and amplifiers the optical signal through nonlinear polarization. The distributed gain medium has zero-dispersion at wavelength lambda0. A magnitude of dispersion at lambda is less than 50 ps/nm-km. One or more semiconductor lasers are operated at wavelengths lambdap for generating a pump light to pump the distributed gain medium. An output port outputs the amplified optical signal.
