The density capabilities of free-space optical interconnects are analyzed by applying Gabor’s theory of information. It is shown that it is possible to increase the space–bandwidth product capabilities of space-variant interconnect schemes if they have symmetry properties. Several examples of such symmetries (locality, separability and smoothness) are discussed in detail, together with some experimental results.
