The core diameter of multimode step index fibre is 60 micrometer. The difference in refractive index is 0.013. The core refractive index is 1.46. Determine the number of guided modes when the operating wavelength is 0.75 micrometer.The core diameter of multimode step index fibre is 60 micrometer. The difference in refractive index is 0.013.

  • \Delta=n1-n2/n1
n12_n22=(n1+n2)=(n1+n2/2)(n1_n2/n1)2n1
n1+n2/2\approxn1
and 
NA=\sqrt{}n122\Delta
therfore
na=n1\sqrt{}2\Delta
v-no. or normalized frequence
v=\pi d/\lambda \sqrt{}}n12_n22
No. of fibre traveling
for step index fibre
N=v2/2
for graded index fibre
N=v2/4
