Abstract
Disclosed are articles and systems that comprise optically communicating logic elements. Exemplarily, a first logic element is a real space transfer logic element having two or more electrical input channels and an optical output channel, and a second logic element has two or more electrical input channels and an optical or an electrical output channel. Associated with at least one of the electrical input channels of the second element are means ('switching means') whose electrical state is responsive to an optical signal that impinges on the switching means (e.g., a photoconductor, phototransistor or photodiode). The elements are arranged such that the output signal of the first element impinges on the switching means, whereby the output of the second element is responsive to the output of the first element. In an exemplary embodiment the inventive article comprises massively parallel signal processing means comprising a multiplicity of optically communicating levels.
