Planar lightwave circuits (PLCs) of all-optical multi-layer switches are presented, where the cycle structure of the spatial switches is modelled by rearrangeable nonblocking pruned rectangular cellular arrays (PRCAs). The chosen network model is the coupled PRCA (CPRCA). However, refined modelling of the proposed MxN-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 (ML) of switches is needed and the (2) multiple use (MU) of directional couplers (DCs) arises, respectively. The PLCs of wide-sense nonblocking dilated multi-layer switches with simple switchsetting are also presented.
