A vast amount of research has been done on optical fibers. Most of the work has been done on Glass optical fibers (GOFs). Much less has been done on Plastic optical fibers (POFs), and very little with regards to applications of nonlinear optics.1 Plastic optical fibers are currently under intense investigation and are used for Local Area Networks (LAN), vehicular systems2 and optical sensor applications. Though they have much greater losses than Glass optical fibers they display advantages with regard to easy fabrication, flexibility, porosity and permeability (sensors), optical modification by organic dyes and cost.
