ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,393,091, issued on Aug. 19, was assigned to Aloe Semiconductor Inc. (Middletown, N.J.).

"Transverse-magnetic polarization silicon-photonic modulator" was invented by Christopher R. Doerr (Irvine, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A silicon-photonic optical modulator includes at least one optical input and at least one optical waveguide that is connected to the at least one optical input. The at least one optical waveguide is configured to propagate quasi-transverse-magnetic (quasi-TM) polarized light, where each of the at least one optical waveguide is configured as a rib waveguide that includes a rib arranged on a slab. The silicon-...
