Latest Patents

One of his latest patents is titled "Optical fiber junction and method of making same." This invention discloses an optical fiber junction device and a method for its production. The method involves providing a central inner pipe or rod of glass, arranging multiple optical fibers around it, and applying external heat to create a thermally fused assembly with cores of a sectorial cross-section. The inner pipe may feature a tapered portion with a reduced diameter, and the optical fibers can consist of junction units made up of several optical fibers.

Another notable patent is the "Liquid level detecting device and method for producing the same." This device is designed to have low transmission loss and can be miniaturized. It comprises several optical fibers, each with a core made of a transparent material and a cladding layer of another transparent material with a lower refractive index. The end portions of these optical fibers are arranged adjacent to each other, either in parallel or at an acute angle. A detecting portion is created by heating the adjacent ends to fuse them together, forming a spherical shape due to the surface tension of the fused material.
