ALEXANDRIA, Va., March 3 -- United States Patent no. 12,567,716, issued on March 3, was assigned to II-VI DELAWARE INC. (Wilmington, Del.).

"Asymmetric chirped fiber Bragg grating for diode laser of fiber amplifier" was invented by Evgeny Zibik (Zurich) and Jeffrey Steven Greatrex (Torquay, Great Britain).

According to the abstract* released by the U.S. Patent & Trademark Office: "A fiber amplifier to amplify seed light has a laser diode, an optical fiber segment, and a doped fiber. The laser diode generates pump light at a pump wavelength from an end facet, and optical fiber segment in optical communication with the pump light has a fiber Bragg grating (FBG) configured to lock the pump light from the end facets to the pump wavelength.
