We demonstrate on-chip all-optical pulse erasure based on four-wave mixing and cross-phase modulation in a dispersion engineered chalcogenide (As2S3) rib waveguide. We achieve an erasure efficiency of similar to 15 dB for picosecond pulses in good agreement with numerical simulations using the nonlinear Schrodinger equation. The combined effect of the high instantaneous optical nonlinearity (gamma = 9900 (Wkm)(-1)) and small group-velocity dispersion (D = 29 ps/nmkm), which reduces pulse walk-off, will enable all-optical pulse erasure for ultrafast signal processing.
