ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,506,555, issued on Dec. 23, was assigned to II-VI DELAWARE INC. (Wilmington, Del.).
"Monitor window in ASE injection seed" was invented by Shaohua Cai (Shanghai).
According to the abstract* released by the U.S. Patent & Trademark Office: "A reconfigurable optical add/drop multiplexer using a wavelength selective switch (WSS) component to multiplex wavelength channels into a wavelength division multiplexed (WDM) signal. When a given channel is dropped, an amplified spontaneous emission (ASE) injection signal is multiplexed as a ghost channel into the WDM signal. The ASE injection channel can mitigate polarization hole burning and can provide a fuller power spectrum density. However, t...
