Paper Abstract

The exact field solution of a step profile fiber was used to determine the injection efficiency of a bulk distribution of sources located in the cladding of an optical fiber. Previous results for weakly guiding fibers were confirmed. We found that, for a fixed V-number, the power efficiency Peff, increases parabolicaly with the difference in the indices of refraction, ncore-nclad. Also, Peff was found to increase with the wavelength (lambda) and decrease with the core radius a.
