A novel programmable all-optical buffer for optical packet switching network

In this paper, a novel all optical buffer based on cascaded double-loop all optical buffer (DLOB) unites is proposed and demonstrated experimentally with the SNR analyze. This buffer is compact, simple, and inherently stable, the delay can be adjusted in the range of 0 to 250us. By injecting a synchronizing control pulse, the operation of reading and writing can be realized easily and the switch time is up to 20ps. The new optical buffer can be used in optical routers to solve the packets contention.
