An electro-optical device for providing spatial modulation of an incoming electromagnetic wave signal, and preferably a two-dimensional incoming signal applied orthogonally to an input plane of the device, which device includes an array of modulation regions for providing such modulation of portions of the incoming signal. An array of first reflective mirrors are positioned so as to direct the incoming electromagnetic wave signal portions through the interaction layer regions of the modulation regions in a direction substantially parallel thereto and an array of second reflective mirrors directs the modulated electromagnetic wave signal portions outwardly from the device to provide a two-dimensional spatially modulated output electromagnetic wave signal.
