Abstract
System and method for generating quantum-entangled photons. First and second laser sources are coupled to each of a plurality of multi-mode optical fibers. The first laser source is coupled into one guided mode and the second laser source is coupled into another guided mode for each of the fibers. Intermodal four-wave mixing the outputs of the fibers separates the signals. A signal combiner recombines the filtered outputs to produce a broadband source of quantum-entangled photons.
