Abstract (en)

A signal switching processor has a plurality of input and output ports, and a number n of signal switching units (7,9) arranged in series between the input and output ports and coupled together so as to generate at each output port a data output signal corresponding to a data input signal supplied to a respective input port. The switching units are mounted in an array of rows, are coupled together by a perfect shuffle optical system (11), and are responsive to received data signals to modulate respective read signals incident on the switching units. Each of the leading n-1 switching units causes the modulated read signals to be reflected towards a respective reflector (25) for subsequent reflection towards the next row in the array of switching units.
