Abstract
We demonstrate on-chip all-optical pulse erasure based on four-wave mixing and cross-phase modulation in a dispersion engineered chalcogenide (As 2S3) rib waveguide. We achieve an erasure efficiency of ∼15 dB for picosecond pulses in good agreement with numerical simulations using the nonlinear Schrödinger equation. The combined effect of the high instantaneous optical nonlinearity (γ = 9900 (Wkm)-1) and small group-velocity dispersion (D = 29 ps=nm km), which reduces pulse walk-off, will enable all-optical pulse erasure for ultrafast signal processing.
