Multicore erbium doped fiber amplifiers

SPIE Proceedings, 2016
ABSTRACT We review recent progress of multi -core erbium -doped fiber amplifiers (MC -EDFA). We confirmed by demonstrating a core -pumped MC -EDFA that MC -EDFs have practical amplification characteristic s and core -to-core crosstalk . Three types of cladding -pumped MC -EDFAs are also reviewed , one uses free space optics, other uses a fiber b undled

Erbium-doped tunable fiber laser

SPIE Proceedings, 2008
The Erbium doped fiber laser (EDFL) has demonstrated to be the ideal source for optical communications due to its operating wavelength at 1550 nm. Such wavelength matches with the low-loss region of silica optical fiber. This fact has caused that the EDFL has become very important in the telecomm industry.

Dynamics of an erbium-doped fiber laser

Physical Review A, 1994
The temporal dynamics of an erbium-doped fiber laser shows various interesting modes of behavior. In the stationary regime, a behavior going from a cw working mode to deterministic chaos through different self-pulsed working modes has been observed.

Erbium-doped phosphate fiber amplifiers

SPIE Proceedings, 2003
In 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 ...

Multicore erbium-doped fiber amplifier

2012 17th Opto-Electronics and Communications Conference, 2012
A multicore erbium-doped fiber (MC-EDF) amplifier for simultaneous amplification in the 7-cores has been developed, and the gain and noise properties of individual cores are studied. For a pump power of 146 mW, the average gain achieved in the MC-EDF fiber was 30 dB, and noise figure was less than 4 dB. The net useful gain from the multicore-amplifler,

Acoustically tuned erbium-doped fiber ring laser

Optics Letters, 1991
We report what is to our knowledge the first narrow-linewidth, continuously tunable laser that uses an acousto-optic filter to achieve a broad tuning range. The unidirectional ring-laser configuration incorporates an erbium-doped fiber amplifier as the gain medium and an integrated, frequency-shift-compensated acousto-optic filter as the tuning element.

Dual-wavelength erbium-doped fluoride fiber laser

Lasers in Medical Science, 2019
The laser source with 3 μm/2 μm output wavelength has many application prospects in clinical medicine, photoelectric countermeasure, and scientific research measurement. An Er3+ doped ZBLAN fiber laser with output wavelength of 2 .8 μm and 1 .6 μm is experimentally studied.

Highly Erbium-doped fibers characterization and modeling for Erbium Doped Fiber Amplifiers in WDM regime

Optical Amplifiers and Their Applications, 2005
Simple experiments are used to determine ion-pairs percentage and macroscopic homogeneous upconversion in highly erbium-doped fibers. Using these parameters in a Giles-based model enable to predict Optical-Power-Conversion-Efficiency of WDM-EDFAs with a fair agreement.

Performance analysis of erbium doped fiber amplifiers

2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009
In this study, gain characteristics of erbium doped fiber amplifiers, EDFAs, which are important elements of optical communications over C and L bands, are examined. The factors that effect the gain of an EDFA are given and the differences among some EDFA designs which operate on various wavelengths are determined.
