The power density per unit wavelength term represents the contribution of the spontaneous emission into the guided mode [12]. We note that in contrast to the linear power equation that appears in "classical" EDFA theory [8], [9], (1) includes additional terms due to the varying refractive index contributions.…”

Abstract-We study pulse propagation in Er 3+ -doped fiber amplifiers (EDFA) within the framework of a spectrally resolved pulse rate-propagation equations model. Our model accounts for the effects of gain dispersion, gain saturation, waveguide and chromatic dispersion, and amplified spontaneous emission. This model allows us to approximate the effects of nonlinear resonant dispersion on short pulse amplification in doped fibers, without reverting to the generalized nonlinear Schroedinger equation. Numerical results of the time-dependent power spectrum of the amplified pulse demonstrate subpicosecond pulse propagation in EDFAs.Index Terms-Erbium (Er), optical fiber amplifiers, optical fiber dispersion, optical pulse amplifiers.

“…While in the four-level system of Nd 3+ , the clusters lower the population density of the 4 F 3/2 manifold due to an increase in the cross-relaxation rate, as well as reduce the number of Nd 3+ ions that interact with Yb 3+ , the three- level Er 3+ clusters absorb the signal that is emitted and amplified by the homogeneous ions. Therefore, the decrease of the NYDFL efficiency due to an increase in the number of clustered ions is less significant than in three-level systems (e.g., see [17]). For example, the maximum efficiency of a system with full clustering (k = 1) is 0.56, for a Nd …”

“…Based on the same length (12 m) of the two fibers, we designed two amplifiers (A-STD and A-RH, respectively) with the same 19 dB gain for a 10 dBm input power. A backward pumping scheme is used in which the 915 nm laser pump and the 1545 nm signal to be amplified propagate in opposite directions [21].…”

Abstract-We present an approach coupling a limited experimental number of tests with numerical simulations regarding the design of radiation-hardened (RH) rare earth (RE)-doped fiber amplifiers. Radiation tests are done on RE-doped fiber samples in order to measure and assess the values of the principal input parameters requested by the simulation tool based on particle swarm optimization (PSO) approach. The proposed simulation procedure is validated by comparing the calculation results with the measured degradations of two amplifiers made with standard and RH RE-doped optical fibers, respectively. After validation, the numerical code is used to theoretically investigate the influence of some amplifier design parameters on its sensitivity to radiations. Simulations show that the RE-doped fiber length used in the amplifier needs to be adjusted to optimize the amplifier performance over the whole space mission profile rather than to obtain the maximal amplification efficiency before its integration in the harsh environment. By combining this coupled approach with the newly-developed RH RE-doped fibers, fiber-based amplifiers nearly insensitive to space environment may be designed in the future.
