Abstract
Experiments were conducted to quantify the amount of light injected from a thin film of fluorescent sources confined at the core and cladding interface of an optical fiber, also referred to as a fluorosensor. Conditions necessary for high injection of fluorescent light, previously predicted by a theoretical model, have now been experimentally verified. The results show that, for side excitation, light injection from the thin-film source into guided modes increases with the fiber diameter and the difference between the core and the cladding refractive indices, ncore − nclad.
