Oscillatory metastability in optical network synchronizer circuits

Synchronization of signal packets is required in networks in order to route the packets. Due to changes in the interarrival times of the packets the i nputs to the routing circuits may exhibit oscillatory metastability. Oscill atory metastability can be eliminated in optical circuits by the addition o f logic signal stretch. This can be done because the propagation time of op tics can be precisely controlled. An algorithm for inserting logic signal s tretch to eliminate oscillatory metastability is presented herein.
