Demonstration of label-rewriting using 1 x 4 all-optical packet switch employing optical processing of scalable in-band labels

Abstract

We demonstrate label-rewriting function using 1times4 all-optical packet-switch that utilizes a highly scalable and asynchronous label processor. Results show that labels are successfully exchanged and the process causes only 0.5 dB power-penalty and error-free operation at 160 Gb/s.
