Latest Patents

Kousuke Yamaki holds a patent for a "Plastic optical fiber and production method thereof." This invention involves a sophisticated process where a cylindrical outer clad section is formed by melt-extrusion molding of polyvinylidene fluoride (PVDF). The molecular structure of the PVDF is designed to ensure that the number of defect bonds of successive CF units and successive CH units constitutes not less than 4% of the total number of bonds. Following this, an inner clad section forming material is poured into the hollow portion of the outer clad section and polymerized to create a cylindrical inner clad section. A core section forming material is then filled into the hollow portion of the inner clad section and polymerized to form the core section. This meticulous process results in a preform that is heat-drawn to obtain a POF with an outer clad featuring small spherocrystals and an average roughness Ra of less than 0.10 µm.
