Abstract

The Pluta polarizing interference microscope is used to measure the refractive index profile and material dispersion of step index optical fiber. the method is explained as well as the theoretical considerations for determination of refractive index. Experimental work is done to measure the refractive index profile of a step index optical fiber at different wavelengths using this technique.
