Abstract

We investigate the feasibility of the use of 1-m length of our fabricated bismuth oxide-based nonlinear fiber (Bi-NLF) for the implementation of a Mamyshev-type 2R regenerator that is based on self-phase-modulation-induced spectral broadening followed by spectral filtering, and evaluate the regeneration performance in both experimental and theoretical ways from a perspective of system application. Owing to the excellent dispersion and Χ(3) nonlinearity characteristics of our 1-m-long Bi-NLF, a nonlinear S-shape power transfer curve is readily obtained. A Q-factor improvement of a noisy 10-Gb/s return-to-zero signal by 1.2 dB is achieved by use of the regenerator.
