Results are reported of realizing optically programmable components of digital processors, a full adder, a space switch‐demultiplexer based on optically bistable vacuum‐deposited semiconductor interferometers (interference filters). Examples are given of arranging coupling between elements and synthesis of loop circuits, RS flip–flop, relaxation generators (clocks). The possibility is shown of performing logical operations with the aid of interference filters in nano‐ and picosecond times. Besides thermal nonlinearity, nonlinearities of electronic nature are considered which are due to size effects in semiconductor microcrystalline films.
