Abstract

1wt% Er 3+-doped 75GeS 2-15Ga 2S 3-10CsI (GGSI) chalcogenide glasses are fabricated and the properties of these glasses are investigated. The mode field distribution in mid-infrared (IR) region of the designed photonic crystal fiber (PCF) is worked out by the multipole method. Based on the rate equations and light propagation equations, the numerical simulations on mid-infrared gain versus the fiber length, pump power and signal power for the Er 3+-doped GGSI chalcogenide glass PCF are presented in this paper, which are compared with those of conventional fiber amplifiers. Effects of energy transfer between Er 3+ levels due to cross-relaxation and cooperative up-conversion are considered here. It is shown that the average signal gain of the Er 3+-doped GGSI chalcogenide glass PCF exceeds 40 dB in the region of 2750-2950 nm, which presents a bigger signal mid-infrared gain than conventional fibers with 20 dB.
