CONTOH SOAL OPTIK

Consider a piece of step-index optical fiber with a refractive index at the fiber core and cladding of 1.48 and 1.46, respectively. (a) Find the refractive index change . (b) What should be the maximum fiber core

diameter if this fiber is designed to be single-mode for wavelength starting from 1,100nm?

(c) Estimate the number of modes if the fiber used for 850-nm laser.
