Consider a step index optical fiber with a core diameter of 50 um and a cladding diameter of 250 um. The core refractive index is 1.475 and the cladding refractive index is 1.445 (a = 900 nm) a. Calculate the V-number for the fiber. b. How many modes are there? b. Calculate the cut-off wavelength above which the fiber becomes single mode.
