摘要: A method is proposed whereby the propagation characteristics of a single-mode fiber having an arbitrary refractive-index profile may be expressed in terms newly defined equivalent step-index profile. The theory based on fact that field distribution HE11 mode closely resembles Gaussian makes it possible to characterize from simple measurement spot size without making difficult index and core radius measurements. It also found suitable for fibers.
