A tunable WDM wavelength converter based on cross phase modulation effects in normal dispersion holey fiber

, 2003
We demonstrate a tunable wavelength-division-multiplexing wavelength converter based on cross-phase modulation in just 5.8m of highly nonlinear normal dispersion holey fiber (HF) and incorporating a precise compression-tuned apodized fiber-grating filter.
