Paper Abstract

An innovative all-fiber low-pedestal spectral compression scheme based on a two-stage structure employing a high nonlinear fiber (HNLF) connected with a nonlinear optical loop mirror (NOLM) is proposed and demonstrated. Both numerical and experimental results showed that the spectral pedestal and side-lobe component after spectral compression in the HNLF can be efficiently suppressed by the NOLM, simultaneously improving the spectral compression ratio. The measured spectral compression ratio increases by a factor of 2 from 3.39 to 6.91 and the side-lobe level is reduced from –7.47 to –9.36 dB. The spectral pedestal ratio is 15.7% using the proposed scheme, which is nearly one-third of that using the conventional feedthrough HNLF alternative.
