Properties of Mode profile Consider the equation for solving the mode profile (electric field) in a planar wave guide (Equation 3.3 in the text book) 0 a) For Ey1(x) and Ey2(x) corresponding to two different values of β show that the functions Ey1(x) and Ey2(x) are orthogonal. b) Show that for slabs with symmetric refractive index profile n(x)= n(‐x), the modal profiles can be chosen to have eith...
