Latest Patents

Yukihiro Sako holds a patent for a method of optically coupling one end of an optical fiber to a waveguide formed on a substrate. This method involves fitting an end portion of the fiber into a groove created in the substrate. The groove is formed using a beam-shielding mask with a cutout, which is aligned with the substrate part where the groove is made. A high-energy beam is then used to irradiate this part of the substrate. Alternatively, the groove can be created using a cutting tool, with the end surface of the groove being irradiated through a beam-shielding mask. The optical fiber's end, which can have a flat face or a coned or hemi-spherical shape, is positioned for optimal coupling with the waveguide exposed to the groove. This innovative method enhances the efficiency of optical connections.
