US Patent Issued to RET and Associates on July 14 for "Wideband hybrid fiber amplifiers and lasers operating in the 2000 nm wavelength region" (Pennsylvania Inventor)

ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,348, issued on July 14, was assigned to RET and Associates LLC (Allentown, Pa.).

"Wideband hybrid fiber amplifiers and lasers operating in the 2000 nm wavelength region" was invented by Robert Ehrler Tench (Allentown, Pa.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A hybrid optical fiber amplifying device is proposed that is based upon a concatenated combination of a section of Tm-doped fiber (TDF) followed by a section of Ho-doped fiber (HDF). The doped fiber sections are configured to be no more than a few meters in length. Using the sections of doped fiber in this order (i.e., TDF followed by HDF) has been found to provide amplification of inp...
