The effect of a modified cladding on the transmission of light through a step-index optical fiber is investigated using 3-D geometrical optics. Measurements of the light transmission of the optical fiber as a function of the modified cladding refractive index and length are presented for the case of focused illumination and compared with 3-D ray theory. The effect of defocus on the transmission of the modified fiber is also studied. Applications to intensity sensors are discussed.
