The Method for Manufacturing Graded-Index Polymer Rod

초록

A method to prepare Graded-index polymer rods which are used in graded index polymer optical fibres (GI-POF) or optical rod lens was discussed. The polymer rod was prepared by utilizing the swelling of the polymers and the diffusion of the monomers in the polymer-monomer mixtures. It was observed that the refractive index of the polymer rod decreased from the center axis to the periphery with minimum fluctuation. It was also found that refractive index profile was appropriate for practical GI-POF applications.
