US Patent Issued to Arizona Board of Regents on Behalf of The University of Arizona on July 15 for "Photonic integrated circuit with squeezed and entangled light generation, and associated methods" (Arizona Inventors)

ALEXANDRIA, Va., July 16 -- United States Patent no. 12,360,431, issued on July 15, was assigned to Arizona Board of Regents on Behalf of The University of Arizona.

"Photonic integrated circuit with squeezed and entangled light generation, and associated methods" was invented by Zheshen Zhang (Tucson, Ariz.), Shuai Liu (Tucson, Ariz.) and Bo-Han Wu (Tucson, Ariz.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A photonic integrated circuit (PIC) includes a first microresonator that generates a two-mode squeezed vacuum using spontaneous four-wave mixing. Specifically, the first microresonator uses a nonlinear optical medium to convert two pump photons into a pair of entangled signal and idler photons. Due to i...
