“…A lot of parameters, such as dopant concentration, fiber length, etc., have a significant impact on the gain performance. Hence it is highly necessary to analyze these parameters theoretically in advance of fabrication (Caccavale et al 1997;Shooshtari et al 1998;Huang and Syms 1999;Zhong et al 2004;Jiang et al 2005;Valley 2001). The parameter range used in our simulation is measured from high gain Er 3+ /Yb 3+ co-doped phosphate glass materials Jiang et al 2005).…”

In this work, a model for analyzing the gain characteristics of heavily Er 3+ /Yb 3+ co-doped compact fiber amplifier is presented. Four-level rate equations and finite-difference beam propagation method are applied to simulate the optical field evolution along the active fiber. Based on this model, the influences of ion concentration, fiber length and pump power on the gain characteristics of Er 3+ /Yb 3+ co-doped phosphate glass fiber amplifiers are theoretically investigated. Numerical results show that for a fiber length of 3.6 cm the internal gain can reach 27.2 dB with N Er = 2.6 × 10 26 ions/m 3 and N Yb = 1.2 × 10 27 ions/m 3 when pumped with 224 mW at 980 nm. The gain per centimeter is 7.56 dB/cm. The results can provide useful information to optimize the gain performance of these compact fiber amplifiers.Keywords Er 3+ /Yb 3+ co-doped fiber amplifiers · Helmholtz equation · Rate equations · Finite-difference beam propagation method (FD-BPM)

Erbium-doped fiber devices have been extraordinarily successful due to their broad optical gain around 1.5-1.6 μm. Er-doped fiber amplifiers enable efficient, stable amplification of high-speed, wavelength-division-multiplexed signals, thus continue to dominate as part of the backbone of longhaul telecommunications networks. At the same time, Er-doped fiber lasers see many applications in telecommunications as well as in biomedical and sensing environments. Over the last 20 years significant efforts have been made to bring these advantages to the chip level. Device integration decreases the overall size and cost and potentially allows for the combination of many functions on a single tiny chip. Besides technological issues connected to the shorter device lengths and correspondingly higher Er concentrations required for high gain, the choice of appropriate host material as well as many design issues come into play in such devices. In this contribution the important developments in the field of Er-doped integrated waveguide amplifiers and lasers are reviewed and current and future potential applications are explored. The vision of integrating such Er-doped gain devices with other, passive materials platforms, such as silicon photonics, is discussed.
