Title:
OPTICAL FIBER AND SOLAR TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/024336
Kind Code:
A1
Abstract:
The purpose of the present invention is to eliminate the necessity for a wavelength filter or power-supply-driven light source unit having a specific wavelength when using sunlight. The present invention relates to an optical fiber in which the periphery of a core is covered by cladding, wherein the optical fiber transmits a predetermined wavelength among the wavelengths included in sunlight, and has a core radius and a difference in the relative refractive index of the cladding with respect to the core.
