▲ [23p-A406-5] Pseudo-disordered tellurite-based oxide fiber
キーワード：Pseudo-disordered fiber, Tellurite, glass
Recently, an all-solid disordered tellurite glass optical fiber with good image transportation was reported [1] on long (10cm) fiber at different wavelength (1.4 to 1.6µm). It is, though, known that the problem of disordered fiber is that image transmission can be distorted due to oversized clusters of fibers of same refractive indices.
This work is trying to find how to obtain better results compared to disordered fiber in view of coupling efficiency or image resolution by using a non-disordered network. To obtain these results, core sizes were randomly chosen with a fixed nearest-neighbour core centre distance (core size of 1.1 to 1.8µm and core centre distance of 3µm) and results were obtained with a beam wavelength of 1.55µm. This presentation will show the evolution of the different simulations to obtain the best possible pseudo-disordered with fixed nearest-neighbour core centre distance network for tellurite glasses.
