“…Since the first demonstration of laser action of Nd 3 + ions in glass [1], an enormous number of works have been carried out on the optical spectroscopy and laser technology of rare earth ions in glasses [2][3][4][5][6][7] and glass fibers [8][9][10][11][12]. Many rare earth-doped glass systems can operate as efficient luminescent materials and solidstate lasers in the visible and the near-infrared spectral regions [13,14].…”

In terms of the coupled mode theory, formulas of the transfer function and the output power gain are presented for an Er 3C /Yb 3C co-doped parallel-cascaded double microring resonator. Around the pump wavelength of 0.98 m and the central signal wavelength of 1.55 m, analysis is performed for the dependence of the output power gain on the pump power, signal power, dopant concentration, amplitude coupling ratio, and ring spacing. The results show that the output power gain of this device is much larger than that of the Er 3C /Yb 3C co-doped waveguide amplifier with identical waveguide lengths. In the case of the amplitude coupling ratio Ä D 0.064, ring spacing L 2 D 10 R, pump power P p0 D 8 mW, signal power P s0 D 37.2 W, Er 3C ion concentration N Er D 1 26 m 3 , and Yb 3C ion concentration N Y b D 3 27 m 3 , the device can produce higher signal power gain from 11.9 dB even up to 70 dB.

“…One of important idea is using nanotechnology for improving amplification process. It was shown that the adding silicon nanocrystals to Er doped SiO 2 strongly enhances the effective Er absorption cross section [3][4][5]. Also, it was shown that nanocrystals doped into fiber causes the excitations of Er ions compared traditional EDFA through a strong coupling mechanism.…”

In this article the details of Erbium doped Fiber Amplifier (EDFA) in presence of Silicon nanocrystal (Si-Nc) is investigated. In this analysis Si-Nc and Er ions in matrix of fiber are assumed two and five levels respectively. For this structure rate equation for transient and steady state analysis is considered. The range of Er (+3) concentration and pump intensity at 488 nm are considered [10 17 − 10 21 ]1/cm 3 and [10 17 − 10 23 ] photon/cm 2 • sec respectively in this paper. Based on numerical simulation of this problem we observed that with increasing of concentration of the Si-Nc the fiber length for given optical gain is decreased. For example in the case of 40 dB optical gain, we calculated fiber length to be 1.1 × 10 5 cm without Si-Nc and 5 × 10 2 cm for σ CCa = 1 × 10 −17 cm 2 (confined carrier absorption cross-section) and 5 cm for σ CCa = 1 × 10 −19 cm 2 respectively. Our simulations show that for second level with increasing pump intensity the population rise and fall times are decreased. But, for third level the population rise time is decreased and fall time is depends to level of Er ion interactions. We observed that with increasing Er ions optical net gain is increased and finally has a maximum. After this special value of Er ions because of increasing in interaction between ions the net gain finally begin to decrease. In this analysis we let to Er ions have inhomogeneous distribution. Also, we observed that in this case with increasing of the distribution peak, the net gain is increased, interaction between ions is increased, the coupling coefficient to the Si-Ncs is increased and losses due to Si-Ncs are decreased. Finally effect of K exiton (maximum number of exciton in single Si-Nc) on amplification process is considered and we observed that in the case of K exiton = 2 the optical gain considerably and introduced losses due to Si-Nc are increased.
