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.
The routing functionality by all-optically interconnecting semiconductor-based all-optical logic gates and flip-flops is demonstrated in the frame of an all-optical label swapping (AOLS) network. We experimentally show that the output of the all-optical 2-bit correlator is capable of toggling the states of the integrated flip-flop every 2.5 ns via an adaptation stage. High extinction ratios are obtained...
A new architecture for an all-optical self-routing packet switch is reported. The experimental results at 40 Gbit/s show a low power penalty and a contrast ratio around 9 dB.
A new architecture for an all-optical N-bit XOR gate with feedback is presented. The simulation results using realistic parameters show error-free operation (Q-factor>8.8) at 10 Gb/s for 8-bit length words.
