Latest Patents

Koudo Yamada holds a patent for a method of manufacturing polarization-maintaining optical fibers. This patent describes a process where two opposite portions of the surface of a core rod, which has a circular section, are removed by machining in the longitudinal direction. This transformation results in a non-circular shape for the core rod. Glass particulates are then accumulated on the surface of this non-circular core rod, which are subsequently sintered to create a preform. The preform is heated and drawn to produce a polarization-maintaining optical fiber with a non-circular section. This innovative method enhances the performance and reliability of optical fibers.
