“…Francisco et al studied both 1550 nm and 980 nm lasers in an erbium-doped fiber amplifier to observe slow light and superluminal propagation in 2011 [9]. In 2013, slow and fast light via two-wave mixing in an ytterbium-doped fiber at 1064 nm were investigated in detail [10]. In 2014, Saini et al simulated two different types of tellurite fibers for tunable slow light generation based on SBS [11].…”

Slow light is demonstrated in the cascade structure of an erbium-doped fiber with two forward propagation pumps. The results of the numerical simulation of the time delay and the optimum modulation frequency complement each other. The time delay and the optimum modulation frequency depend on the pump ratio G (G = ). The discussion results of this paper show that a larger time delay of slow light propagation can be obtained in the cascade structure of Er3+-doped optical fibers with dual-frequency laser pumping. Compared to previous research methods, the dual-frequency laser-pumped cascade structure of an Er3+-doped optical fiber is more controllable. Based on our discussion the pump ratio G should be selected in order to obtain a more appropriate time delay and the slowdown of group velocity.

“…Dynamic population gratings recorded via local saturation of the optical absorption or gain in maxima of the interference pattern of two mutually coherent optical waves counter-propagating in the rare-earth-doped fibers [1,2] can have different promising applications. In particular, their utilization in tunable extra-narrow-band optical fiber filters [3,4], singlefrequency fiber lasers [5][6][7], different configurations of adaptive interferometers [8,9], and slow/fast light propagation [10,11] via two-wave mixing (TWM) were demonstrated. Characteristic rate of the recording/erasure of these gratings is governed by the life-time of the active ion metastable state (about 10 ms [12] in erbium-doped fiber (EDF) and about 1 ms [13] in ytterbium-doped fiber) and usually grows with the recording light power in the 1-10 mW region [2].…”

Formation of the dynamic population gratings in optical fibers with randomly oriented rare-earth ions is analyzed with a special interest to the grating component for readout with the orthogonal light polarization. It is shown that as compared with a simple model case of the collinearly oriented dipole-like centers their random orientation leads to approximately 2-times growth of the effective saturation power P sat when it is estimated from the incident power dependence of the fiber absorption or from that of the fluorescence intensity. An optimal incident power, for which the maximum of the dynamic population grating amplitude for collinear light polarization is observed, also follows this change in P sat , while formation of the grating for orthogonal polarization needs essentially higher light power. The reduced anisotropy of the active centers, which is in charge of the experimentally observed weakening of the polarization hole burning (PHB) and of the fluorescence polarization, compensates in some way the effect of random ion orientation. The ratio between the maximum conventional (i.e. for the interacting waves collinear polarizations) two-wave mixing (TWM) amplitude and the initial not saturable fiber optical density proves to be, however, nearly the same as in the model case of collinearly oriented dipoles. The ratio between the PHB effect and the amplitude of the anisotropic grating, which is responsible for TWM of the orthogonally polarized waves, is also not influenced significantly by the reduced anisotropy of ions.
