Abstract

Photo-polymerization is the reaction between monomers to form polymer chains, and these polymer chains have a higher refractive index than the monomer in the photopolymer, and so it is higher in the polymerized areas. There are four main processes that occur during photo-polymerization in the photopolymer, which are Initiation, Propagation, Termination, and Inhibition. Self-written waveguides (SWWs) in photopolymers, and the process of self-focusing and self-trapping, has been seen that certain important areas which require further research. In this article, the effect a SWW has on the transmission of light through the photopolymer is further tested using a PVP as a media with Rhodamine 6G (R6G) as a dye. Simulations were focused on investigating the SWW mechanism, testing different quantities of beams entering the material. The SWW process was seen to be of most interest for the connection and splitting of multiple optical waveguides.
