Performance of duo‐stage SOA based all‐optical multicasting switching matrix for future grid networking

This paper presents the performance evaluation of a duo‐stage SOA based All‐Optical Multicasting capable Switch architecture suitable for the requirements of Grid Networking. SOAs based devices are located at the input and the output ports of the switch. The SOAs located at the input port serves as a multicasting and routing device feeding the signals into an N × N arrayed waveguide gratings and the SOAs at the output are regenerators to restore the quality of the signals before sending them into the network. This design uses the non‐linearity processes in SOA such as Cross Gain Modulation and Cross Phase Modulation to achieve a maximum of 1–16 multicast at a bit‐rate of 10 Gbps within the all‐optical switch. © 2006 Wiley Periodicals, Inc.
