Abstract
- In this paper, the absorption characteristics of a novel double-clad gain-guided and index-antiguided (GG-IAG) fiber are investigated with 3D ray-trace method. Additionally, the simulated correctness compared with real data was carried out by measuring the GG-IAG fiber. Analysis and experimental results show that the absorption characteristics of GG-IAG fibers are different from conventional fibers: the total absorption efficiency of a GG-IAG fiber is large, while the effective absorption length is very short, and the negative refractive index step has significant influence on the total absorption efficiency.
