摘要

本文设计并优化了一种新型Tm:Er:Yb:Ho共掺锗酸盐玻璃光纤放大器，泵浦波长为λp = 980 nm，在λ = 1.4 ~ 2.1 μm波长范围内实现宽带/三波段放大。初步研究表明，光增益与掺杂浓度、光纤长度和泵浦功率有关。为了获得合适的三波段增益，采用粒子群优化算法进行全局优化。

Wideband optical amplifier based on Tm:Er:Yb:Ho co-doped germanate glass

In this paper, an innovative Tm:Er:Yb:Ho co-doped germanate fiber glass amplifier, pumped at λp = 980 nm, is designed and optimized, to obtain a wideband/three band amplification in the wavelength range λ = 1.4 – 2.1 μm. A preliminary investigation has shown the dependence of the optical gain on the dopant concentrations, the fiber length and the pump power. To obtain a suitable three-band gain, a Particle Swarm Optimization (PSO) algorithm is applied in order to perform a global optimization.
