Core has higher refractive then cladding
WebMay 14, 2024 · To confine the optical signal in the core, the refractive index of the core must be higher than that of the cladding. I failed to understand how and why does … WebA higher core index, with respect to the cladding, means larger NA. However, increasing NA causes higher scattering loss from greater concentrations of dopant. A fiber’s NA can be determined by measuring the divergence angle of the light cone it …
