ALEXANDRIA, Va., Aug. 26 -- United States Patent no. 12,399,312, issued on Aug. 26, was assigned to The Penn State Research Foundation (University Park, Pa.).

"Recursion-based design for suppressing inter-fiber cross-talk in multi-core fibers" was invented by Mikael Caleb Rechtsman (Boalsburg, Pa.), Jonathan Guglielmon (State College, Pa.) and Kevin Peng Chen (University Park, Pa.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Embodiments relate to generating a configuration of waveguide propagation constants formed in a waveguide array system. The configuration of propagation constants can be made via a recursive detuning process that produces approximations to a fractal structure designed to maximally loca...
