Optimization of pump efficiency of Er(3+)-Ce(3+)doped telluride fiber amplifier.
We propose a simplified numerical model to simulate the erbium/cerium codoped telluride fiber amplifier, and the feasibility of this model is verified by comparing the numerical results with the experiment data. Based on this numerical model, the research of the erbium/cerium codoping concentration and fiber length indicates that 45?dB gain can be achieved at a pump power of 130?mW for a 15?cm length telluride fiber.
