US Patent Issued to Analog Photonics on May 27 for "Phase front shaping in one and two-dimensional optical phased arrays" (Massachusetts Inventors)

ALEXANDRIA, Va., June 17 -- United States Patent no. 12,313,953, issued on May 27, was assigned to Analog Photonics LLC (Boston).

"Phase front shaping in one and two-dimensional optical phased arrays" was invented by Ehsan Hosseini (Boston) and Michael Watts (Hingham, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along ...
