<p>An optical processor includes a non-linear spatial light modulator defining an array of logic gates and having an output plane 10 and an input plane 12. The array is made up of a plurality of cells 14 each containing a plurality of logic gates 16. A lenslet array 18 comprising an array of lenslets 20 associated one with each cell 14 respectively focusses the outputs of the cells onto respective facets 22 of a holographic array 24. Each facet of the holographic array defines a predetermined mapping or routing configuration to may the respective cell onto the input plane 12. The cells may be mapped either precisely onto the predetermined cell of the input plane or in cell-shifted fashion. An optical processor is described which employs the arrangement illustrated in Figure 1 to enable assembly of a plurality of similar interacting modules for implementing a regular algorithm such as a fast multiplier array.</p> |
