Consider an asymmetric planar waveguide with nf=1.5, ns=1.47, nc=1.0. Determine the allowed values of beta for the TE modes in a waveguide with thickness h=7 micrometers. Assume the excitation wavelength is 1 micrometer.
Our prof gave us this equation;
Beta = (Ko2nf2-Kf2)1/2
Ko =(2pi/lambda)n
But which n do we use in this case and similarly for Kf.
