$Q1) A step-index fiber having a 25 um core radius, n=1.48, and n=1.46. a) Find the numerical aperture. b) Find the normalized frequency at 820 nm. c) How many modes propagate in this fiber at 820 nm. Q2) Use an appropriate software program to plot the refractive index profiles n(r) as a function of the radial distance r for graded index fibers that have profile parameters a values of 2, 6, and 12. The fibers have n =1.49 (at fiber axis), A=0.01 and core radius a= 30 pum. (plot for - 2a <r<2a).$
