Abstract

Abstract The analysis of waveguides with refractive index profiles containing Dirac delta functions is described. Although unphysical, such profiles are limits of real multiple-layer waveguides and are much simpler to analyse. The presence of a delta function in the profile is found to lead only to the modification of one boundary condition.
