Abstract :
We report on integrated optics Ti:LiNbO/sub 3/-based 8/spl times/8 switch matrices. The matrix design uses a tree structure with 112 digital optical switches as switch elements. The matrix, which has been pigtailed and packaged in an open package for convenient system demonstrator use, exhibits a worst case insertion loss of less than 15 dB.<>
