WebNov 17, 2024 · This diagram corresponds to multimode propagation with a refractive index profile that is called step index. As you can see, the diameter of the core is fairly large relative to the cladding. There is also a sharp discontinuity in the index of refraction as you go from core to cladding. WebThe R-IGIF features a shape parameter $\alpha$ that controls the refractive index behavior (i.e. concave vs convex). We performed a systematic scanning of parameter' effects; using finite...
