Reconfigurable time-domain de-multiplexing of optical signals at 40 Gb/s

We experimentally demonstrate reconfigurable switching of four 10-Gb/s tributary channels of 40-Gb/s data using a programmable planar lightwave circuit and nonlinear wavelength conversion. Our device is a silica-on-silicon based 6-stage lattice-form Mach-Zehnder interferometer.
