ALEXANDRIA, Va., Sept. 15 -- United States Patent no. 12,739,037, issued on Sept. 15, was assigned to PSIQUANTUM CORP. (Palo Alto, Calif.).
"Multiplexing for photonic circuits" was invented by Terence Rudolph (San Francisco) and Hugo Cable (Palo Alto, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Circuits and methods can implement reconfigurable spatial rearrangement (also referred to as "spatial multiplexing") for a group of photons propagating in waveguides. For instance, two sets of small optical multiplexer circuits (such as two sets of 2x2 optical multiplexer circuits or two sets of 3x3 optical multiplexer circuits) can be used to rearrange a pattern of photons on a first set of waveguides into ...
