“…Therefore, in practice, the solution of complex active medium equations, whether it is an analytical or numerical solution, inevitably requires simplifications and approximations. Ignoring some of less significant transitions in the active medium, a set of equations reported to be successfully modeling the amplifier regime [1] and purely theoretical works investigating the implications of these simplifications have been reported [2,3].…”

“…Recent research on emission properties of Er 3+ -Tm 3+ codoped and Pr 3+ -Er 3+ co-doped fibers showed that the combination of the emission at 1530 nm window due to Er 3+ : 4 I 13/2 → 4 I 15/2 transition with the emission at 1470 nm window due to Tm 3+ : 3 H 4 -3 F 4 transition may generate a larger seamless emission spectrum up to 200 nm in the codoped system [7][8][9][10][11][12]. Meanwhile, the research on emission properties of Pr 3+ -Er 3+ co-doped fiber showed that the combination of the emission at 1530 nm window due to Er 3+ : 4 I 13/2 → 4 I 15/2 transition with the emission at 1310 nm window due to Pr 3+ : 3 F 4 -3 H 5 transition may generate an emission spectrum having two peaks centered at 1310 nm and 1530 nm windows [7][8][9][10][11][12][13].…”

We present for the first time a theoretical model of Er 3+ -Tm 3+ -Pr 3+ codoped fiber pumped with both 800 nm and 980 nm lasers to explore possibility of this co-doped system as all-wave fiber amplifier. The rate and power propagation equations of the model are solved numerically and the dependence of the gains at 1310, 1470, 1530, 1600, 1650 nm windows on fiber length is calculated. The results show that with pump power of 200 mW/200 mW, when the concentrations of Pr 3+ , Tm 3+ , Er 3+ are around 1.7 × 10 24 , 3.9 × 10 24 , 1.2 × 10 24 (ions/m 3 ), respectively, the signals at 1310, 1470, 1530, 1600, 1650 nm may be nearly equally amplified with gain of 13-16.0 dB in the active fiber with length of 23.5 m; the co-doping concentrations and fiber length and pump powers may be further optimized to reduce the ripple.

“…The incorporation of Yb 3+ significantly increases laser stability against cluster-driven self-pulsation [11,12]. The distributed Bragg reflection (DBR) Er/Yb co-doped single-frequency fiber laser based on fiber Bragg gratings (FBGs) is simple and inexpensive, and the configuration of laser is conveniently integrated into a wavelength-division multiplexing all-optical network [13,14].…”

A 5-cm-long Er/Yb co-doped all-fiber laser is studied. Two fiber Bragg gratings (FBGs) are written in the Er/Yb co-doped sensitive fiber using UV beams. A 980 nm pumping laser diode (LD) is used, and output wavelength is selected by two FBGs. The single-frequency laser is achieved at 1544.68 nm. The 3 dB spectrum width is 0.08 nm, while the side mode suppression ratio is 55 dB. The maximum output power exceeds 4 mW for pump power of 140 mW and the stability is less than ± 0.01 dB. Single-frequency operation is verified using a scanning Fabry-Perot (F-P) interferometer. Relative intensity noise is less than -100 dB. A 10 Gbit/s code rate is used in the fiber laser transmission experiment. A good optical eye diagram is received after 21 km single-mode fiber transmission. A simple distributed Bragg reflection (DBR) fiber laser array is designed. The wavelength difference of output laser array is 0.8 nm, conforming to the ITU-T channel spacing standard of wavelength-division multiplexing systems.
