Studies on the light-focusing plastic rod 16: Mechanism of gradient-index formation in photocopolymerization of multiple monomer systems

Abstract

In this paper, we propose a general mechanism for forming a radial GRIN rod by photocopolymerization in multiple monomer systems and a method of selecting new monomer systems applicable to GRIN. By using the simulation with various monomer systems, it is shown that the index distribution of a plastic GRIN rod can be tightly controlled by the selection of a ternary monomer system and the photocopolymerization condition.
