We examine the theory of optical amplification in long span single-mode fibers which have low levels of erbium dopant. When pumped from the transmitter end at a suitable wavelength, lightly doped fibers can form a distributed amplifier, capable of overcoming transmission losses due to the intrinsic attenuation of the host glass at the signal wavelength.

SPIE Proceedings, 1991
Recent progress on an erbium-doped optical fiber amplifier (EDFA) pumped with a 0.98 micron laser diode is reported. An erbium-doped fiber with a very high gain coefficient of 11.0 dB/mW has been achieved using an extended VAD method. A high power 0.98 micron laser diode with a strained-layer InGaAs quantum well laser structure has been developed as ...

Broadband Fiber Optic Amplifiers
Optical Fiber Communication Conference and International Conference on Quantum Information, 2001Broadband fiber optic amplifiers are key elements of DWDM systems and enablers for optical networks. New amplifier technologies for extending gain-bandwidth and equalizing the power deviation among WDM signals are discussed toward the next generation of ultra.-high-capacity DWDM systems.

Integrated ytterbium-Raman fiber amplifier
Optics Letters, 2014An integrated ytterbium-Raman fiber amplifier architecture is proposed for power scaling of a Raman fiber laser. It is an ytterbium (Yb) fiber amplifier seeded with a double or multiple wavelength laser and followed by a passive Raman fiber. The bluest wavelength light gets amplified in the Yb fiber and the power is transferred to redder wavelengths in

Amplifier/compressor fiber Raman lasers
Annual Meeting Optical Society of America, 1987When pump and Stokes pulses copropagate in a fiber Raman laser (FRL), the weaker Stokes spectrum is severely broadened through pump-induced cross-phase modulation (XPM).1 Thus, in an FRL during Raman amplification, the pulse is chirped through XPM, and then the linear anomalous dispersion of a fiber can compress the pulse.

Broadband fiber optical parametric amplifiers
Optics Letters, 1996The bandwidth of a single-pump fiber optical parametric amplifier is governed by the even orders of fiber dispersion at the pump wavelength. The amplifier can exhibit gain over a wide wavelength range when operated near the fiber's zero-dispersion wavelength. It can also be used for broadband wavelength conversion,with gain.

Theoretical investigation on Raman Fiber Amplifiers
Asia Communications and Photonics Conference and Exhibition, 2010The characterization of RFAs with bi-directional Raman pumped or co-propagating Raman pumped is studied. The effection to RFAs for pump power, initial signal power and fiber length is analyzed, which is to optimize and improve gain of RFASSs, so as to improve the performance of the amplifier.
