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 ...

Fiber-based phase-sensitive optical amplifiers and their applications
, 2020Optical parametric amplifiers rely on second-order susceptibility (three-wave mixing) or third-order susceptibility (four-wave mixing) in a nonlinear process where the energy of incoming photons is not changed (elastic scattering).

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

Annual Meeting Optical Society of America, 1988
Recently there has been a renewal of interest in the use of fibers doped with optically active ions, principally rare earths, as active devices in optical fiber communications and sensor systems. This increase in activity has been driven by improved methods for incorporating dopants into telecommunications-grade fiber, the availability of laser pumps ...

Summary form only given. Wavelength-division multiplexing (WDM) transport networks require amplifiers allowing large channel counts along with large span distances. This means that high gain (>25 dB) and large output power is required, along with low noise figure, in order to ensure high channel signal-to-noise ratio. Hence, for a 2.5-Gbit/s line-rate,

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
This study presents the principles behind a fiber parametric amplifier (FPA) operation. This includes the discussion of parametric amplification, four-wave mixing, phase conjugation, wavelength conversion, and optical regeneration due to gain saturation. FPA applications for quantum-optical systems and optical processing are also discussed.

Optical fiber amplifiers for telecommunication systems
IEEE Communications Magazine, 1996Optical amplification is of strategic importance for telecommunications. Optical amplifiers compensate for propagation losses in long distance links and branching losses in access networks, at the same time avoiding costly two-way conversions between optical and electrical signals.

One of the most important technical advances in fiber optic telecommunication systems has been the optical fiber amplifier (OFA). The use of an all-optical fiber optic amplifier instead of a semiconductor optical amplifier has many inherent advantages.
