Gain, 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 کاملHigh Gain Erbium Doped Fiber Amplifiers
Performance improvements by using an isolator as an amplified spontaneous emission suppressing component within erbium-doped fibers are evaluated. Simultaneous high-gain and near-quantum-limited noise figures can be obtained by such a scheme. The noise figure improves for input signal powers below -5 dBm and an improvement of 2.0 db with a simultaneous gain increase of 4.1 dB is measured relati...
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 کاملTunable gain-clamped double-pass Erbium-doped fiber amplifier.
A tunable, gain-clamped (GC) double-pass Erbium-doped fiber amplifier (EDFA) with a linear laser-cavity configuration has been demonstrated. It solves the problems existing in the conventional linear-cavity GC-EDFA based on two fiber Bragg gratings (FBGs), in which the clamped-gain is very difficult to be tuned. In the new GC-EDFA, the lasing oscillation for clamping the gain is produced in a l...
متن کاملChirped 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...
