Abstract

Many communications systems require routing of data packets (binary strings of 100 bits or more) from any of many sources to any of many receivers. Typically, each packet comprises its destination address in its "header" string. Examples where such routing is needed include dataflow machines, LANs, WANs, telecommunication, etc. It is here proposed to use an integrated optoelectronics "routing" chip to accomplish the data routing. A typical embodiment of the invention is given as follows: A number, N2 (say, N=8), of solid-state lasers with driver circuits and N2 p-n photodetectors with amplifiers and signal detectors are integrated on a chip (e.g., GaAs, Ga-In-As-P). The lasers can be of the type described in an article in Electronics Week of June 3, 1985, pages 30-34.
