Wavelength conversion of high-speed phase and intensity modulated signals using a highly nonlinear chalcogenide glass chip
We report all-optical wavelength conversion of high-speed differential phase-shift keyed (DPSK) and ON-OFF keyed (OOK) signals using the nonlinear Kerr-effect in an optical chip. This was enabled by four-wave mixing (FWM) of the signal with a continuous-wave (CW) pump laser in a 7-cm-long dispersion-shifted planar rib waveguide in highly nonlinear As2S 3 glass. Both conversion of 40-Gb/s DPSK and 160-Gb/s OOK signals by 33 and 15 nm, respectively, are shown. These are first demonstrations of...[Show more]
