Single-mode optical fiber

摘要

An optical fiber includes a central core, which has a radius r 1 and a refractive index n 1 , and a surrounding optical cladding, which has a refractive index n 2 such that n 2 <n 1 and 0.31%<((n 1 −n 2 )÷n 2 )<0.55%. The optical cladding has at least five holes. These holes, which are positioned between about …
