The feasibility of a microstructured optical fiber (MOF) amplifier, made of a novel Er-doped chalcogenicle glass, has been demonstrated via accurate simulations performed by employing an oppositely implemented computer code. The optical and geometrical parameters measured on the first MOF sample together with other physical constants from literature have been taken into account in the simulations. The calculated optical gain of the optimized MOF amplifier, 2.79 m long, is close to 23 dB at the signal wavelength of 1.538 mu m, by using a pump power of 200 mW and a signal power of 0.1 mu W.
