WebFigure 1: A single-mode fiber has a core which is very small compared with the cladding, whereas a multimode fiber can have a large core. The waveguiding properties are determined by the refractive index profile, i.e., the increase in refractive index in the core relative to that of the cladding. For step-index profiles, the numerical aperture and the V …
