Paper Abstract

There are a number of applications for optically addressed SLM's which benefit from grey scale capability. We are particularly interested in input devices for optical correlators; programmable beam deflectors; and soft threshold units for neural net architectures. The requirements for each application have a different emphasis. For optical correlators, a high photosensitivity and good dark state are important. For beam deflection, a linear transfer characteristic will assist the formation of a replicate sine wave grating and optimal diffraction efficiency. Finally, soft threshold units require a nonlinear transfer characteristic. It is the suggestion of this paper that a single electro-optic effect in the light modulating layer of the light valve might be useful for each of these several applications. Then we present experimental measurements on two examples of light valves, with particular relevance to the third application.
