Ultra-High Nonlinear As$_2$ S$_3$ Planar Waveguide for 160-Gb/s Optical Time-Division Demultiplexing by Four-Wave Mixing

A low loss As2S3 planar waveguide with ultra-high optical Kerr nonlinearity ~2000 W-1 ldr km-1 and only 50-mm length demonstrates high-performance time-division demultiplexing of a 160-Gb/s signal into its tributary 10-Gb/s channels via four-wave mixing (FWM) with copropagating pump pulses. Although the waveguide has a high normal dispersion parameter, its combined high nonlinearity in such short length is shown to enable efficient FWM of high-speed optical signals for all-optical demultiplexing.
