Description
Summary:Cold plasma of power 13W has been applied on step index plastic optical fibers. It is used to study the ability for any variations in the optical parameters that are effective in communication. The effect of plasma on the optical parameters, such as core index profile, cladding index and the numerical aperture, has been studied by multiple beam interference fringes. The interference fringes have been processed using a homemade Matlab written program to get more accurate measurements. It is found that there is an increase of 1.5839 in core index, at core-clad interface, with a plasma exposure time of 150 sec.
