Paper Abstract

This paper reports an application of a rainbow technique to characterize both the core and cladding diameter of a single, silica-based, step-index optical fiber. Both quantities are inversely calculated using a correlation formula from the farfield scattering pattern where multiple primary rainbows occur. A set of observations of scattering allows one to retrieve the parameters of interest. Numerical studies assume variable core (10–50 μm) as well as cladding diameter (120– 130 μm). A part of analysis shows how the temporal coherence of the incident beam of light affects the solutions.
