A large scale optical switch array based on guided-wave technology using banyan network architecture is demonstrated. Banyan network architecture is the simplest NN network connecting a input port to all the output ports. A banyan network optical switch array serves as a base for constructing many classes of switch networks, as we propose in this report. We fabricated a 3232 switch and measured its characteristics. Drive voltage was about 12 V and extinction ratio was 18 dB, and the average insertion loss was 18 dB. Preliminary experiments were conducted on a 6464 device. The use of proton exchanged waveguides makes a 10 mm radius of curvature feasible.
