Felton A Flood, David Jacob, Mark F Krol, Edward F Murphy, Peter G Wigley: Optical amplifier designs for multichannel fiber optic communication networks. Corning Incorporated, William Greener, Svetlana Short, October 17, 2000: US06134047 (17 worldwide citation)

A multichannel fiber optic communication network incorporates multichannel fiber optical amplifiers having different functions but designed to use substantially identical gain flattening filters. This is achieved by designing the amplifiers to have total insertion losses such that their respective i ...

Gregory J Cowle, Douglas W Hall, Thomas W McNamara, Chiachi Wang: Optical amplifier with power dependent feedback. Corning Incorporated, Svetlana Short, January 15, 2002: US06339495 (16 worldwide citation)

An optical amplifier includes an optical feedback resonant laser cavity (OFRC) including a power dependent loss element (PDLE) having the characteristic that as the incident laser power on the PDLE increases the cavity loss decreases. The OFRC with the PDLE provides optical gain control or optical p ...
