17 April 1998High-bandwidth and high-thermal-stability graded-index polymer optical fiber
Recent progress of the graded-index polymer optical fiber (GI POF) is reviewed. Because the low attenuation of light transmission in the perfluorinated (PF) polymer base GI POF enables 500 to 1000 m transmission, more accurate analysis is required in the refractive index profile to realize the order of giga bit transmission. The analytical procedure of the bandwidth characteristics of the GI POF is described in this paper. Furthermore, recent improvement of the thermal stability of the GI POF is introduced. We clarified that the stability of the refractive index profile and the attenuation under high temperature and high humidity atmosphere can be improved by selecting the suitable dopant material.
