Abstract :
Efficient time-division demultiplexing using two different wavelengths, one for the signal and one for the control beam, has been implemented in an AlGaAs nonlinear directional coupler at 1550 nm. This all-optical demultiplexer makes use of cross-phase modulation and walk-off between the two wavelengths to give high contrast at both low and high powers and to eliminate the pulse break-up. Additionally, ultrafast wavelength shifting has been observed
