We present a theoretical model describing a pixellated, optically bistable, interference filter illuminated by a Gaussian beam. Preliminary experiments using ZnSe devices and 514-nm wavelength radiation show good agreement with this model for pixels of area 80×100 µm2 and a depth of 60 µm. Critical powers and cooling rates are presented for different combinations of materials and pixel dimensions.
