ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,422,258, issued on Sept. 23, was assigned to Anello Photonics Inc. (Santa Clara, Calif.).

"Ring waveguide based integrated photonics optical gyroscope with balanced detection scheme" was invented by Mario Paniccia (Santa Clara, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The present disclosure relates to integrated photonics-based optical gyroscopes with silicon nitride (SiN) waveguide-based microresonators. SiN microresonators are fabricated either on a fused silica platform or on a silicon substrate with oxide cladding. A narrow linewidth high-Q laser is hybridly integrated on a silicon photonics platform. The laser is tuned with a first Si...
