Chapter 13, Problem 13.29P
An asymmetric slab waveguide is shown in Figure 13.26. In this case, the regions above and below the slab have unequal refractive indices, where n1 > n3 > n2. (a) Write, in terms of the appropriate indices, an expression for the minimum possible wave angle, 81, that a guided mode may have. (b) Write an expression for the maximum phase velocity a guided mode may have m this structure, using given, or known parameters.
