An efficient gain-flattened C-band Erbium-doped fibre amplifier is demonstrated using a double-pass configuration with an IsoGain^TM^ Erbium-doped fibre (EDF). The amplifier utilizes a double-propagation of signal provided by an optical circulator at the output end of the EDF to obtain an improved f

Abstract
This paper reports on dynamically gain‐flattened C‐ and L‐band erbium‐doped fiber amplifiers (DGF‐EDFAs), whose dynamic gain ranges are above 20 dB and 24 dB, respectively. This paper gives the detailed test and comparative results for DGF‐EDFAs based on the use of a voltage‐controlled fiber‐based gain tilt controller and a variable optical attenuator. © 2003 Wiley Periodicals, Inc.

A new hybrid erbium-doped-fiber design is proposed for amplifiers with flattened gain spectra. The design prescribes different parts of the erbium-doped fiber core to be codoped with different materials. Due to specific relations between the codopant material and their emission and absorption spectr
## Abstract A new double‐pass long‐wavelength‐band erbium‐doped fiber amplifier with enhanced noise figure characteristics is demonstrated by adding a short length of forward pumped erbium‐doped fiber (EDF) in front of the double‐pass amplifier. By adding 7 m of EDF, the amplifier achieves a flat‐g
## Abstract We show experimental performance comparison of different equalization methods in erbium‐doped optical amplifiers based on silica and ZBLAN host materials. Different configurations are analyzed, including the analysis of hybrid silica/ZBLAN configurations, exploring gain, bandwidth, and
## Abstract A new design of an all‐optical gain‐clamped erbium‐doped fiber amplifier is demonstrated. The amplifier is based on the conventional ring cavity, where the gain is clamped at 21.84 dB via optical feedback using a single fiber Bragg grating for an input signal power as high as −8 dBm. ©
