Abstract

The all-optical regeneration technique about return-to-zero (RZ) optical data streams can be implemented by self-phase modulation (SPM). Highly nonlinear fiber (HNLF) is the medium in which both the discrete Raman amplification and self-phase modulation can be implemented. Co-pumped Raman amplification has been demonstrated to enhance self-phase modulation and reduce greatly the pulse signal power which is used to SPM in HNLF. The relation between the spectral bandwidth of the pulses broadened by SPM and the chirp of the pulses is also researched in theory and so is the relation between the spectral density of the SPM-broadened spectrum and pulse intensity, the result is that they are independent when the dispersion length is very longer than the HNLF length. Thus the all-optical data regeneration can be implemented by using band-pass filter which its pass frequency ω_p offset the signal frequency ω₀ and spectral bandwidth Δω_p. The regenerative performance can be enhanced by the discrete Raman amplification.
