Dual-cavity Optical Gain Control for EDFAs and EDFA Cascades
Optical Amplifiers and their Applications, 1999Optical wavelength-division-multiplexed networks will need provisions for partially altering the traffic at each repeater by adding/dropping some service channels.

Conference on Optical Fiber Communication, 1994
We propose a new parameter to describe the noise performance of erbium-doped fiber amplifiers (EDFAs). ft is based on the fact that the noise of a laser amplified by an EDFA is very similar (formally and substantially) to the noise of a laser with a higher relative intensity noise (RIN).

Conference on Optical Fiber Communication, 1994
In long-haul communications, erbium-doped fiber amplifiers (EDFAs) operate at a particular wavelength to produce the optimal level of dispersion. The gain spectrum of the ions can be used to filter the accumulated amplified spontaneous emission in such a system.1 To optimally use this autofiltering, the gain-peak wavelength (GPW) of the chain must ...

Broadband EDFA With Flat Gain Response
Conference on Lasers and Electro-Optics Europe, 1996Dense WDM techniques in lightwave networks increase transmission capacity and improve system flexibility. Gain flatness of conventional EDFAs limits the number of WDM channels. Several techniques1,2 for EDFA gain equalization have been investigated, but with various shortcomings.

Challenges in the Design of Few Mode EDFAs
Optical Fiber Communication Conference, 2016We review recent results on optical amplifiers for space division multiplexing transmission. We emphasize on the importance of crosstalk characterization for few mode EDFA and present an amplified five mode transmission over 80km.

Comparison of laboratory measurements on an EDFA with simulation results obtained using EDFA-Design
Proceedings of 2001 3rd International Conference on Transparent Optical Networks (IEEE Cat. No.01EX488), 2002A comparison of measurements and simulations on an erbium-doped fiber amplifier (EDFA) is given. A commercial program (EDFA-Design(R)) was used for the simulations. Measurement results were obtained during the MSc. project of the corresponding author in the Institute of Telecommunications and Acoustics in Wroclaw University of Technology.
