Abstract

Fast packet switching is an important technology for multimedia communication. Further increases in switch throughput will be accomplished by using photonic technologies.¹ Optical packet receivers are indispensable for photonic packet switching systems, however, and the incoming signal power fluctuates with every packet due to the loss imbalance of optical paths. To resolve this problem, optical packet receivers with feedback control, for example, highspeed automatic-gain-control (AGC) have been proposed and demonstrated.² However feedback control cannot operate at a speed comparable to signal bit rates.
