Patent number: 8743454Abstract: An optical amplifier includes at least one pump source and an optical fiber cable which includes an amplifying optical fiber and a pump optical fiber that are defined by respective lengths. The amplifying optical fiber and the pump optical fiber are coated with a common coating along a portion of their respective lengths, and the fibers are in optical contact with each other along a coating length within the common coating. The common coating has a refractive index which is lower than a refractive index of a cladding material of the pump optical fiber. The fibers are made substantially from glass. The amplifying optical fiber includes a core and a cladding, and is doped with a rare earth dopant. The pump optical fiber is defined by a first end and a second end, the first end of the pump optical fiber being connected to the pump source.Type: GrantFiled: August 21, 2012Date of Patent: June 3, 2014Assignee: SPI Lasers UK LtdInventors: Anatoly Borisovich Grudinin, Dave Neil Payne, Paul William Turner, Lars Johan Albinsson Nilsson, Michael Nickolaos Zervas, Morten Ibsen, Michael Kevan Durkin

Patent number: 8270070Abstract: An optical fiber arrangement has at least two optical fiber sections, each optical fiber section defining an outside longitudinally extending surface. The outside longitudinally extending surfaces are in optical contact with each other. The invention further provides for an amplifying optical device have an optical fiber arrangement as just described, and a pump source. The amplifying optical device is configured such that the pump source illuminates the amplifying optical fiber. A amplifying arrangement is also disclosed. The amplifying arrangement includes a plurality of amplifying optical devices as just described, and each amplifier also has at least one input fiber and a first multiplexer connected to the input fiber. Each amplifier is configured such that at least one of the amplifying optical fibers is connected to the first multiplexer. The amplifying arrangement also has a second multiplexer connected to each of the first multiplexers.Type: GrantFiled: February 8, 2010Date of Patent: September 18, 2012Assignee: SPI Lasers UK LtdInventors: Anatoly Borisovich Grudinin, Dave Neil Payne, Paul William Turner, Lars Johan Albinsson Nilsson, Michael Nickolaos Zervas, Morten Ibsen, Michael Kevan Durkin
