Latest Patents

Valkonen holds a patent for an optical fiber structure and a method of producing it. This invention includes an optical waveguide that consists of a core, a buffer surrounding the core, and a cladding surrounding the buffer. The materials used for the core, buffer, and cladding are silica glass. Notably, the refractive index of the buffer is substantially equal to that of pure amorphous silica glass. This design helps to reduce bubble formation during manufacturing and facilitates the splicing of the waveguide. Additionally, the numerical aperture of the waveguide can be fine-tuned by adjusting the radial dimension of the buffer, compensating for variations in the refractive index of the core.
