“…Furthermore, it is possible to estimate the power threshold for SBS according to Eqs. (5) and (6) since this is of interest for telecommunication. All the derived properties mentioned above are shown and compared in Table 2.…”

“…When the pump linewidth is very narrow, the term in brackets tends toward unity, which gives the minimum of Eq. (5). This shows that SBS can become an important phenomenon in this case, which happens sometimes in telecommunications, where SBS is considered a nuisance.…”

“…These characteristics have led to a great number of applications, such as in fiber lasers [3,4], amplifiers [5], laser cooling [6], super continuum laser [7], among others. The advantage of ZBLAN over other conventional glasses such as silica for fiber fabrication is its superior infrared transparency.…”

“…With the expressions of (15)-(19), the (12)- (14) can be calculated directly as: (24) Table 1 shows the parameters used in our numerical analysis where the signal absorption, emission and ESA cross section are obtained from the literature [15]. Based on the model and these parameters, we numerically estimate the signal gain, ASE versus wavelength and input power as shown in the following section.…”

In this paper, we first deduce a model of Praseodymiumdoped fiber amplifiers using the transitions between different energy states and the rate equations. Base on this model, the characteristics of Praseodymium-doped fiber amplifiers are investigated numerically. An experimental Praseodymium-doped fiber amplifier operating around 1300 nm is implemented to verify the model. The measurements of this amplifier, which has small signal gain of 16 dB, bandwidth of 27 nm, and amplified spontaneous emission noise less than -33 dBm, agree with the model quite well. Because many cable television systems are operating around this wavelength, we apply a Praseodymium-doped fiber amplifier to a cable television system with both analog and digital signals. The experimental results show that the changes of the carrierto-noise ratio, composite-second-order distortion, composite-triple-beat distortion and bit error rate of the system with and without the amplifier are insignificant.

A large-signal model for a four-level laser system has been used to study the small-signal and large-signal properties of a praseodymium-doped fluoride fiber amplifier. The model takes into account the LP 01 mode radial field distribution in step-index single-mode fiber and experimentally obtained stimulated emission, signal excited state absorption and pump absorption crosssections. It has been found that the optimum cutoff wavelength is 750 nm and is independent of numerical aperture and input pump power. The numerical aperture should be made as high as possible.
