- W2370745341 abstract "To improve the gain characteristics of optical waveguide amplifier,the paper introduces the development of the theoretical model of the Yb-Er co-doped waveguide amplifier gain,based on the level structure and energy transfer process of the Yb-Er co-doped system,offers the numerical simulation results of the gain characteristics,and discusses the influence of erbium ion doping concentration,pump optical power and signal optical power on optical waveguide amplifier gain coefficient.The numerical simulation results show that when the waveguide length is less than its optimum value,the gain coefficient significantly increases with increase in erbium ion doping concentration and pump optical power.The waveguide length greater than the best waveguide length leads to gain fall.For the same pump optical power,increase in the signal optical power triggers decrease in the gain.The pump optical power of 70 mW gives an optical waveguide amplifier the length of 2.24 cm a gain per unit length of 4.73 dB/cm,and this result is basically consistent with the experimental data." @default.
