Title: Per Stenius: Innovator in Optical Fiber Technology

Introduction

Per Stenius is a notable inventor based in Espoo, Finland. He has made significant contributions to the field of optical fiber technology, holding 2 patents that showcase his innovative approach to waveguide design and light amplification.

Latest Patents

Stenius's latest patents include an "Optical fiber structure and a method of producing thereof." This invention features an optical waveguide that consists of a core, a buffer surrounding the core, and a cladding surrounding the buffer. The materials used include silica glass, with the buffer's refractive index closely matching that of pure amorphous silica glass. This design helps 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 to compensate for variations in the core's refractive index.

Another significant patent is the "Light amplifying fiber arrangement." This arrangement includes a pump fiber made of glass and a bridge element, with portions of both components fused together. The active fiber features a light-amplifying core and a first cladding, also made of glass. The second cladding surrounds both the pump and active fibers, effectively confining pump light. This innovative design allows for easier splicing of pigtails compared to conventional doubly clad fibers, enabling the coupling of high power levels into the pump fiber.
