Latest Patents

Hiroshi Betsui's latest patents showcase his expertise in optical waveguide technology. His first patent, titled "Optical waveguide and manufacturing method thereof," describes a sophisticated optical waveguide structure consisting of a lower clad layer, a core layer, an upper clad layer, a substrate, and a mirror. This innovative design allows for the transmission of light signals irrespective of the substrate type, while also minimizing the spread of light signals reflected by the mirror, achieving low optical transmission loss. Notably, the substrate features an opening with a maximum diameter of 240 μm or less, which is larger than the luminous flux reflected by the mirror.

Another noteworthy patent is entitled "Optical waveguide with mirror, optical fiber connector, and manufacturing method thereof." This invention builds upon his previous work by integrating a mirror formed on an inclined surface of a core pattern, surrounded by a lower clad layer and an upper clad layer. An opening with an approximate pillar shape, designed on the upper clad layer, enhances the optical performance of the waveguide, contributing significantly to the field of optical communication.
