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.
A 1 times 4 all-optical packet switch is presented, based on an optical label swapping technique that utilises a scalable label processor and a label rewriter with 'on the fly' operation. Experimental results show error- free packet switching with a data payload at 160 Gbit/s. The label erasing and new label insertion operation introduces 0.5 dB of power penalty. These results indicate a potential...
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...
We present a fully-packaged, hybrid-integrated all-optical flip-flop with separate optical set and reset operation. The flip-flop can control a wavelength converter to route 40 Gb/s data packets all-optically. The experimental results are given
