We present two paradigms to realize all-optical packet switches, and report experimental results showing the routing operation of the 160 Gb/s packets and beyond. Photonic integrated sub-systems required to implement the packet switch are reviewed.
Two different paradigms to realize a scalable all-optical packet switch with label swapping will be presented. All the functions required for switching the packets are based on all-optical signal processing without any electronic control. This allows very low latency and potential photonic integration of the systems. We report for both techniques experimental results showing the routing operation...
We investigate the feasibility of a 1×4096 optical-packet-switch (OPS) operating at 160Gb/s, by cascading two 1×64 OPSs in a fat-tree configuration. We find error-free operation with 5.7dB penalty over the complete system.
We present a scalable, low latency optical packet switch for optical packets with multiple modulation formats. Results show error-free operation of 1×8 optical packet switch for 160Gb/s RZ-OOK, 320Gb/s NRZ-OOK and 100Gb/s DPSK multi-colored packets.
We present two paradigms to realize a scalable and low latency all-optical packet switch. We report for both techniques experimental results showing the routing operation of the 160 Gb/s packets and beyond. Photonic integrated sub-systems required to implement the packet switch are reviewed.
We present two all-optical packet switching techniques that utilize all-optical signal processing to implement the label processor and the label rewriter. The two techniques are based on two different paradigms. One is based on wavelength routing switching [1] and the other one on space routing switching [2]. Both techniques employ scalable and asynchronous label processor and label rewriter capable...
We present an all-optical 1x4 packet-switch by using scalable label processor and label rewriter. Label erasing/reinserting operation show 0.5 dB of penalty in two-cascaded node configuration.
We demonstrate an all-optical scheme for routing radio signals through optical fibres employing label-processing technique. 10-MS/s 64-QAM signal carried on 5-GHz RF carrier was successfully routed with EVM of 1.81%.
We demonstrate for the first time 160 Gbps error-free 1times4 all-optical packet switching including all-optical label rewriting. Power penalty 1.5 dB enables application in multihop packet-switched networks.
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.
Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. We present a 1times4 all-optical packet switch based on label swapping technique that utilizes a scalable and asynchronous label processor and label rewriter. The packet address information is encoded...
