Space-variant holographic optical elements for switching networks and general interconnects

Optical interconnects enable the transmission of signals with ultra high frequencies with small crosstalk and rather low waste energy per transmission line. Two fields of application for optical wiring concepts can be discerned, i.e. fixed pattern chip to chip (or board to board) interconnects and reconfigurable switching networks or bus systems where the interconnect path is selected out of a number of fixed interconnects by means of e.g. so-called exchange bypass modules (EBM)1,2.
