US Patent Issued to II-VI DELAWARE on Feb. 25 for "Wavelength-division-multiplexing optical circuit implemented in photonic integrated circuit for optical transmitter" (New Jersey Inventors)

ALEXANDRIA, Va., Feb. 26 -- United States Patent no. 12,237,913, issued on Feb. 25, was assigned to II-VI DELAWARE INC. (Wilmington, Del.).

"Wavelength-division-multiplexing optical circuit implemented in photonic integrated circuit for optical transmitter" was invented by Po Dong (Morganville, N.J.) and Argishti Melikyan (Marlboro, N.J.).

According to the abstract* released by the U.S. Patent & Trademark Office: "An optical circuit is used with continuous wave signals having different wavelengths at a channel spacing from one another. A portion of the optical circuit is implemented in a photonic integrated circuit. Modulators in a modulation stage modulate the continuous wave signals to produce modulated signals. A multiplexing stage, wh...
