Error-free wavelength conversion via cross phase modulation in As2S3 chalcogenide glass rib waveguides

We report the first demonstration of error free all-optical signal processing at telecommunication data rates in chalcogenide glass waveguides. We achieve error-free wavelength conversion via cross-phase modulation in a low-loss, 5 cm long As
