Bistability of erbium-doped fiber laser
Optics Communications, 1998In this paper, we report a study of the dynamic response of an erbium-doped fiber ring laser. When the pump light is sinusoidally modulated with small modulation index, the lasing light displays a resonant peak at a particular modulation frequency. However, as the modulation index was increased, two regions of bistability were observed. Furthermore, by

A Distributed Erbium Doped Fiber Amplifier
Optical Fiber Communication, 1990To date erbium amplifiers have been based on fiber doped with 10 to 1000 ppm erbium oxide, providing several tens of dB gain in lengths of 100 m or less.[1–4] However, communications systems which use such high gain, "lumped" amplifiers subject the signal to large excursions in amplitude, which can cause significant interchannel interference in a ...

Nonlinearities in Erbium Doped Fiber Amplifiers
Optical Amplifiers and their Applications, 1999In recent years, cross talk induced by the nonlinear properties of optical fibers has been recognized as an important limiting factor in the performance of wavelength division multiplexed (WDM) systems.

Study of Erbium Doped Fiber Amplifier
2017Optical fiber amplifier is key enabling technology used for high speed optical communication. One of the Amplifiers is Erbium Doped Fiber Amplifier, Which is modeled using the propagation and two level or three level rate equations. The performance of amplifier is depends on various parameters like, Er3+ concentration, fiber length, pump and Signal ...

Erbium-doped phosphate fiber amplifiers
SPIE Proceedings, 2003In this paper, the development of phosphate glass fiber amplifier with a high gain per unit length is reviewed. The performance of compact multimode pumped erbium-doped phosphate fiber amplifiers is presented. A fiber amplifier with a small signal net gain of 41dB at 1535nm and 21dB over the full C-band was demonstrated using a newly developed 8-cm ...
