ALEXANDRIA, Va., Jan. 20 -- United States Patent no. 12,531,647, issued on Jan. 20.
"Intensity-based optical multiplexing systems and methods" was invented by John Paul T. Hansen (Burien, Wash.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method for multiplexing optical signals for transmission over a communication link includes receiving a set of input optical signals. Each input optical signal has an optical intensity at a given time in one of at least two amplitude states. The method further includes selectively adjusting the optical intensity of the input optical signals so that each input optical signal has a respective specific optical intensity for each of the at least two amplitude states.
