Compact, low insertion loss 16/spl times/16 optical switch-array modules

摘要

Switch-array module should exhibit low insertion loss, low cross talk, as well as small size and low cost. We have developed two types of low-loss 16 x 16 LiNbO/sub 3/ optical waveguide switch array modules. The first type of switch is a re-arrangeable non-blocking switch array using a dilated-Benes configuration. The second type of switch is a strictly non-blocking switch array using a tree configuration.
