Abstract
Planar lightwave circuits (PLCs) of all-optical multi-layer switches are presented where the cycle structure of the spatial switches is modeled by rearrangeable nonblocking pruned rectangular cellular arrays (PRCAs). The chosen network model is the coupled PRCA. However, refined modeling of the proposed M X N-gon prism switches causes, beside coupling, additionally, the embedding of small PRCAs into larger ones and their intersection. Dependent on the implementation of PLCs of PRCAs (ordinary, reversed and combinations) the (1) moving location of switches is needed and the (2) multiple use of directional couplers arises, respectively. The PLCs of wide-sense nonblocking dilated multi-layer switches with simple switch setting are also presented.
