Document Type and Number:
WIPO Patent Application WO/2023/228743
Kind Code:
A1
Abstract:
An optical fiber comprising: a core (10) made of silica glass; and a cladding (20) that is made of silica glass and that surrounds the core (10), wherein Δ1-Δ2≥0.02 is satisfied, where Δ1 represents the greatest value of the specific refractive index difference of the core (10) in 0≤r/a≤0.3, and Δ2 represents the smallest value of the specific refractive index difference of the core (10) in 0≤r/a≤0.9, where r represents the radial distance from the center axis of the core (10), and a represents the radius of the core (10).
