ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,442,762, issued on Oct. 14, was assigned to IMRA America Inc. (Ann Arbor, Mich.).
"Optical millimeter-wave oscillator disciplined by rotational spectroscopy" was invented by Antoine Jean Gilbert Rolland (Longmont, Colo.), James Greenberg (Boulder, Colo.), Brendan Heffernan (Boulder, Colo.) and Rubab Amin (Longmont, Colo.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A photonic millimeter-wave oscillator is based on a heterodyne beatnote of two continuous wave lasers and is configured to provide a narrow linewidth output when the frequency difference is disciplined with rotational spectroscopy of molecules using frequency modulation spectroscopy."
