Notes:
Based on the CROSSBAR network (CN) and the BANYAN network (BN), two newrearrangeable nonblocking constructions of extended BANYAN network (EBN) are proposed forimplementing 8×8 optical matrix switch. The interconnection characteristics of these two types ofrearrangeable nonblocking EBN were studied, and the logic program for driving switching unitswas provided. The calculated insertion loss was 3.3 dB for 8×8 optical matrix switch. Silicawaveguide 8×8 matrix optical switch was designed and fabricated according to the calculatedresults. The silica waveguide propagation loss of 0.1dB/cm and waveguide-fiber coupling loss of0.5dB/point were measured. With the fabricated 8×8 matrix optical switch, optical insertion loss of4.6 dB, cross-talk of -38 dB, polarization dependent loss of 0.4 dB, averaged switching power of1.6 W, and switching time of 1 ms were achieved. A basic agreement between experimental resultsand theoretical calculated values was achieved
