We experimentally demonstrate that the use of only 1-m length of our fabricated Bismuth oxide-based nonlinear fiber readily allows for implementing a high-performance 10-Gb/s nonreturn-to-zero signal wavelength converter based on cross-phase-modulation-induced polarization rotation. No stimulated Brillouin scattering (SBS) suppression scheme was employed owing to a high SBS threshold of the fiber. Our wavelength converter is shown to provide a pattern-inverted or a noninverted output signal in the same configuration depending on the relative polarization directions between the probe and the polarizer. Error-free wavelength conversion over a 30-nm bandwidth is readily achieved for both cases, i.e., noninverted and inverted patterns.
