NONLINEAR POLARIZATION AMPLIFIERS IN NONZERO DISPERSION SHIFTED FIBER

摘要

A broadband fiber transmission system includes a transmission line with at least one zero dispersion wavelength lambda 0 and transmits an optical signal of lambda . The transmission line includes a distributed Raman amplifier that amplifies the optical signal through Raman gain. One or more semiconductor lasers are included and operated at wavelengths lambda p for generating a pump light to pump the Raman amplifier. lambda is close to lambda 0 and lambda 0 is less than 1540nm or greater than 1560 nm.
