Weak-guidance approximation

Abstract

In Chapter 13 we showed how to construct the fields of bound modes on weakly guiding waveguides using simple physical arguments, and then, in Chapter 25, we extended the method to include radiation modes. To complement the physical approach, we now give the formal mathematical derivation using perturbation theory on the vector wave equation.
