Erbium Ytterbium Co Doped Fiber Amplifier

Unlike other cladding pump or dual clad fibers fibercore s dual clad erbium ytterbium doped fiber f cp1500y was originally designed as a high power communications amplifier fiber.

Erbium ytterbium co doped fiber amplifier.

The high gain phosphate optical glass fiber amplifiers are integrated onto substrates to form an integrated optics. We report on single frequency all fiber amplifiers based on er yb doped p 2 o 5 al 2 o 3 sio 2 fibers. However a high concentration erbium ion may result in a pair induced quenching effect which potentially reduces the pump power conversion efficiency and increase the noise figure for an erbium doped fiber amplifier edfa. Fiber based lasers and amplifiers utilizing erbium ytterbium co doped fibers have experienced a great progress over the past 15 years thanks to their eye safety they outperform the most popular solid state nd yag or yb doped fiber sources in scientific military or medical applications.

The core of a silica fiber is doped with trivalent erbium ions er 3 and can be efficiently pumped with a laser at or near wavelengths of 980 nm and 1480 nm and. When ixfiber was created in 2006 most of the team had some experience with erbium ytterbium co doped double clad fibers. Our proprietary design ensures high gain and excellent po. 1020 and 0 9 x2013 2 1 x00d7.

Peak power up to 1120 w at 1545 nm for 108 ns pulse duration has been obtained with 18 slope efficiency. We report on the fabrication and optical characterization of erbium ytterbium co doped aluminum oxide al2o3 er3 yb3 waveguides using low cost low temperature deposition and etching steps. The pump light is guided within an all silica structure using a fluorinated secondary cladding to create the pump guide boundary without the need for low index. We deposited al2o3 er3 yb3 films using reactive co sputtering with er3 and yb3 ion concentrations ranging from 1 4 x2013 1 6 x00d7.

An optical fiber amplifier utilizing a phosphate glass optical fiber highly doped with rare earth ions such as erbium to exhibit high gain per unit length enabling the use of short fiber strands to achieve the needed gain in practical fiber optical communication networks. Erbium ytterbium co doped fiber amplifiers eydfa are typically used in high power optical amplifiers. Erbium yterbium doped fiber amplifier 1u eydfa c data eydfa series are mainly used in am catv digital catv fttx pon which is a high power multiport output optical fiber amplifier it s spectral bandwidth is in 1540 1563nm whichis mainly designed for catv or 1 8 itu wavelength. The pump current of the ytterbium doped fiber amplifier is adjustable through the instrument s front panel allowing the user to vary the gain and output power of the amplifier.

The active fiber with high doped erbium ion concentration is used to compensate for the short gain medium length.
