Abstract
We demonstrate recognition of time-stacked multiwavelength (M- <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">lambda</i> ) weight-2 code labels using four-wave-mixing (FWM) sideband allocation and selective optical filtering. At the forwarding node, the labels are separated using a highly reflective fiber Bragg grating and the FWM terms are generated using a highly nonlinear semiconductor optical amplifier. We show successful forwarding of packets through a two-hop network. We report error-free transmission (bit-error rate <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><</i> 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-10</sup> ) of the payload through the entire network with less than 1.5-dB power penalty.
