Did you know?
網頁2024年8月26日 · In a graded index fiber, the refractive index at the center of the fiber is the highest. This means that the light traveling at the center of the fiber travels slower. … 網頁It is known that graded-index fibers (GIF) provide efficient Raman conversion of multimode radiation into a Stokes beam with improved beam quality known as Raman beam cleanup effect, whereas in step-index fibers (SIF) this effect is weak. Here we study propagation of low-coherent (~5 nm wide) highly-multimode (M2~30) pump radiation of high power 940 …
網頁2024年10月1日 · Thus, V of our custom graded-index, graded-index and step-index tapered fibre is 4.9, 9.9 and 10.9, respectively, i.e., V is < 20 for our tested tapers and wave optics solutions will be required. The COMSOL 5.6 wave optics module was used to model the tapers in 3D and the results are shown in Fig. 2 . 網頁Generally, graded-index multimode fiber is used in comparatively less bandwidth and short-haul applications LANs (local area networks) which runs at 1 Gbps otherwise less. …
網頁2024年11月5日 · 定义 Step-index fiber：可以理解为纤芯(core)是均匀的(uniform)，即折射率保持为一个值。 Graded-index fiber：可以理解为core的中心到包层(cladding)的折射率分布是一个梯度的，即渐变的，通常从core的中心向cladding方向，折射率逐渐变小。 光纤截面图 … 網頁3.
