Modes. A step-index fiber has radius a 5 um, core refractive index n = 1.45, and fractional refractive-index change A = 0.002. Determine the shortest wavelength Xe for which the fiber is a single-mode waveguide. If the wavelength is changed to Ac/2, identify the indexes (I, m) of all the guided modes.
