Apparatus for scattering light using optical fiber and sleeve
The patent US11982835B2 describes an innovative apparatus designed for scattering light, which consists of an optical fiber and a sleeve. The optical fiber features a core and cladding, while the sleeve, which is shorter than the optical fiber, is made from a fiber-optic material that has a higher or equal volumetric coefficient of thermal expansion compared to the optical fiber. Notably, the sleeve is polymer-free and has a refractive index greater than that of the cladding. The outer surface of the sleeve is roughened to facilitate light scattering, and it is engineered to ensure that there are no gaps or air bubbles between the sleeve and the optical fiber along their entire length.
Additionally, the patent outlines various configurations and methods for constructing the apparatus. It includes provisions for a filler material that can be placed between the optical fiber and the sleeve, as well as a housing that may contain multiple chambers for enhanced functionality. The design also incorporates features such as a lens, a light-absorbing material, and a residual light catcher to manage light that escapes from the sleeve. The method of forming the apparatus allows for flexibility in the roughening process of the sleeve's outer surface, which can occur at different stages of assembly. Overall, the patent presents a comprehensive approach to light scattering technology, emphasizing material properties and structural integrity to optimize performance.
