Abstract
The effect of a modified cladding on the transmission of light through a step index optical fiber is investigated, using geometrical optics and proper choice of ray cor e-cladding encounters. Measurements and analysis of the light transmission of the optical fiber as a function of the modified cladding refractive index and length are presented for various input illuminations: Focused and defocused incident beams, effect of offset, polychromatic illumination and illumination with a single mode fiber. Applications to intensity sensors are discussed.
