Chirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system OPTICS COMMUNICATIONS
As in bulk amplifiers, the onset of nonlinear effects when amplifying ultra-short pulses in fiber amplifiers has been pointed out and investigated by several groups, specifically in erbium-doped fiber amplifiers ( EDFAs) [ l-3 1. Researchers have in fact used the Kerr nonlinearity in conjunction with group velocity dispersion in order to create even shorter pulses via higher-order soliton forma...
متن کاملErbium-Doped Fiber Amplifier Review
This paper is describing and investigating four crucial areas of Erbium Doped Fiber Amplifier (EDFA). First is the atomic part, where it is meaningful to give deep and details information of erbium spectra structure and its energy level. The atomic spectrum is one crucial part in defining and understanding amplification phenomena. The second part based on understanding, investigating and analyz...
متن کاملGain, Noise Figure and Efficiency Characteristics of an L-Band Erbium Doped Fiber Amplifier
In this work, the construction of a single stage L-band erbium-doped fiber amplifier which incorporates a short 5.1 m erbium doped fiber coil is described. Gain and noise figure measurements as a function of forward, backward and counter-propagating CW 1480 nm pumping schemes at different pump power levels are presented. Further, the Erbium Doped Fiber Amplifier (EDFA) power conversion efficien...
متن کاملOptimization of an erbium-doped fiber amplifier with radial effects
Applying an inversing method and a genetic algorithm, two radial distributions, i.e., a core graded-index and erbium-doped concentration, are optimized for an erbium-doped fiber amplifier (EDFA) in a two-level model under single-mode condition and weakly guided approximations. There is evidence to show that the core graded-index has obvious influence on the gain bandwidth of the EDFA, and simil...
متن کامل[ME01] An Efficient and Low Noise L-band Erbium-Doped Fiber Amplifier
Introduction The use of the long-wavelength-band (Lband) is attractive for both increasing the capacity of wavelength division multiplexing (WDM) systems and has been used in WDM transmission experiments at over 1 Tb/s. Recently, a gain bandwidth of about 80nm has been achieved by integrating the L-band EDFA in parallel with conventional band (Cband) EDFA [1]. Moreover, the L-band EDFAs will ma...
