A micro-optical building block system for optical processing of light signals and method for making the components used in the system. The basic system includes a master substrate on which is mounted at least one building block. Typically, there are a multiplicity of pre-defined positions at which the building blocks will mate with the master substrate. Building blocks can be positioned adjacent to each other on the master substrate in such a way as to allow light signals to be transferred between them. Mating relief patterns are formed on both the master substrate and the building block substrates the, relief pattern areas on the master substrate being adjacent and repetitive, or …
