Abstract

The on near Gaussian-shaped spectrum Erbium-doped fiber super-flourescent source was studied.The self-coherence function of Gaussian-shaped spectrum and the change of mean wavelength under different temperatures were theoretically analyzed.Using the double-pass forward configuration,the Gaussian-shaped spectrum was obtained with certain Erbium-doped fiber length.Meanwhile,pump powers could be adjusted to optimize the intrinsic thermal coefficient of Erbium-doped fiber.Finally,under the condition with erbium-doped fiber length of 10.05 m,LD power of 172 mW,the whole optical path(except pumping LD and the driving) in the environmental temperature from-40 ℃ to 60 ℃,the near Gaussian-shaped spectrum Erbium-doped fiber source with 66.651 ppm mean wavelength stability was obtained.

Theoretical study on erbium ytterbium co-doped super-fluorescent fiber source

Wentao Guo, Feng Du, Manqing Tan +2 more

Erbium ytterbium co-doped super-fluorescent fiber source (EYD-SFS) has been simulated by a theoretical model based on rate equations and power transfer equations. The output performances of four basic structures of EYD-SFS have been expressed, and it indicated that the DPF structure is a preferable structure. The dependence of output power, mean wavelength and bandwidth stability on the pump fiber length and the concentration of Er 3+ and Yb 3+ have also been studied. The results indicated with a proper doping concentration of Er 3+ and Yb 3+ of 6.0 × 10 26 ions/m 3 and 1.0 × 10 27 ions/m 3 , the optimal gain fiber length is 3.6 cm. In this condition, good performances of DPF structure of EYD-SFS have been achieved.

High-Stability Superfluorescent Fiber Source Based on an Er 3+ -Doped Photonic Crystal Fiber

Chengxiang Liu, Li Zhang, Xu Wu +1 more

A superfluorescent fiber source (SFS) based on an Er 3+ -doped photonic crystal fiber (EDPCF) is reported. Owing to the temperature insensitivity of the EDPCF, we show that it is possible to improve the mean wavelength stability of an SFS. Using single-backward configuration, the EDPCF SFS mean wavelength variation at temperatures from −40°C to 60°C is less than 100 ppm, indicating that the thermal coefficient of the EDPCF is smaller than 1 ppm/°C and 3–6 times smaller than those of two conventional Er 3+ -doped fibers under the same experimental conditions. The best performance of the EDPCF-based SFS is obtained between 0°C and 60°C, at which the change in the mean wavelength is only 17.445 ppm.

The Gain Characteristics and the Optimum Fiber Length of Erbium-doped Fiber Amplifiers

Huang De, Li Zai

An apporoximative theoretical of an erbium-doped fiber amplifier (EDFA) has been proposed in this paper by the rate equation of three-level system. The optimum fiber length is obtained with different pump wavelength by considering the excited-stated-absorption(ESA) in EDFA. The relations between the gain and signal light intensity and pump light intensity are analyzed. It is found that the gain spectrum shape can be changed with the fiber length, which provides the evidence that EDFA is of great potential use in wavelength division multiplexed telecommunication systems.

Study of the complex atomic susceptibility of erbium-doped fiber amplifiers

E. Desurvire

A study of the complex atomic susceptibility of erbium-doped fiber amplifiers operating near the 1.53- mu m transition (/sup 4/I/sub 13/2/-/sup 4/I/sub 15/2/) developed from a semiclassical theoretical description is presented. Expressions for the emission cross section sigma /sub e/( lambda ) and absorption cross section sigma /sub a/( lambda ) of erbium:glass as a quasi-three-level laser system with Stark-split sublevel manifolds are derived. The results are used to calculate the cross sections of aluminosilicate erbium-doped fibers at low temperatures (T=4.2, 77 K) and at room temperature. It is demonstrated that an expression for the gain coefficient of the fiber amplifier can be derived from the expression of the susceptibility. Using Kramers-Kronig relations, an expression for the refractive index change in the fiber is derived. The theoretical spectral gain profile of the fiber amplifier and concurrent refractive index changes are analyzed for different pumping regimes.>
