Design and simulation of microptical devices (spot displacement devices) for free-space all-optical OXC systems

We introduce two new designs for a spot displacement device (SDD) to be used in a White cell-based binary optical cross-connect system (OXC). We described in detail the implementation of an SDD based on a lens train configuration and a roof prism SDD. We discuss the aberrations associated with each design. We also show simulations for an eight-output OXC binary system using one of these designs
