Numerical Simulation and Performance Optimization of the Gain Characteristic of EY-CDWA Optical Waveguide Amplifier

Abstract:

The gain model of the Yb-Er codoped optical waveguide amplifier as well as the gain equation has been established based on the analysis of energy level structure of Yb-Er codoped system and the related transition utilizing the rate and transmission equations, and then simulation of the gain characteristic has been carried out. Some most important parameters influencing the gain of the optical waveguide amplifier are discussed and the correlative conditions are optimized. Through numerical simulation, the parameter optimization scheme has been proposed, with which the pump wave length, power and the gain of the amplifier are optimized synchronously, and the maximum gain under the optimum length is obtained. Experimental results show good accordance with the numerical simulation.
