All optical wavelength conversion via cross phase modulation in chalcogenide glass rib waveguides
We demonstrate all-optical wavelength conversion in a 5 cm As2S3 chalcogenide glass rib waveguide with 5.4 ps pulses over a wavelength range of 10 nm near 1550 nm. We present frequency resolved optical gating (FROG) measurements that show good converted pulse integrity in terms of amplitude and phase in the frequency and time domains. The short interaction length ensures that dispersion induced walkoff does not hinder the conversion range of the device.
