Abstract

We experimentally demonstrate the use of our fabricated 1-m-long Bi 2O3 optical fiber (Bi-NLF) with an ultra-high nonlinearity of ∼1100 W-1km-1 for wavelength conversion of OTDM signals. With successfully-performed fusion splicing of the Bi-NLF to conventional silica fibers an all-fiber wavelength converter is readily implemented by use of a conventional Kerr shutter configuration. Owing to the extremely short fiber length, no additional scheme was employed for suppression of signal polarization fluctuation induced by local birefringence fluctuation, which is usually observed in a long-fiber Kerr shutter. The wavelength converter, composed of the 1-m Bi-NLF readily achieves error-free wavelength conversion of an 80-Gbit/s input signal
