The LP modes of a step-index fiber are obtained by solving the eigenvalue equation Eq.(4) (see the manual). Eq. (4) is of the form f() = 0; the roots of this equation are found using the matlab function fminbnd().

In a step-index fiber, core index = 1.45, cladding index = 1.442, core radius a = 9 microns, wavelength = 1.55 microns.
2a.1. Plot the field vs radius for all the modes.
2a.2. Plot V vs b curves for LP01, LP11 and LP03 modes. Using this curve, find the cutoff wavelength for the single-mode operation of a fiber with = 1.46 and Δ =0.005.
