Light transmission through a modified cladding optical fiber - inverse problem analysis

Research output: Contribution to journalArticlepeer-review

Abstract

A method for deriving the angular power distribution of various sources which are used to inject light into an optical fiber is suggested. This distribution can be obtained from the optical power carried by meridional bound rays in a fiber whose cladding refractive index can be modified. The theoretical analysis, which indicates that optical power measurement errors must not exceed 1% in order to obtain reasonably accurate power distributions, is augmented by experimental results. In particular, the case of lens illumination and the estimation of the mode field diameter of a single mode fiber are studied in detail.
