TL;DR: In this paper, a simple exact implementation of Fourier operators is introduced and used for analysing reflection and transmission at open dielectric waveguide discontinuities, including the laser facet.

TL;DR: In this article, a radiation mode technique was used to study the propagation of waves in practical optoelectronic devices and validated against other techniques for step discontinuities, tapers, air gap and Y junctions.

TL;DR: In this article, exact and variational Fourier transform methods for the analysis of generalised planar waveguide structures are described in detail, and specific structures of technological importance, namely the rib and channel waveguides and the rib waveguide directional coupler are presented.

TL;DR: In this article, a Fourier operator was used to derive an exact closed-form eigenvalue equation for the scalar mode propagation constants of a buried rectangular dielectric waveguide.

TL;DR: In this article, the propagation constants and electric field profiles for dielectric multilayered channel (rib) waveguides were obtained for a particular channel configuration and found to be in excellent agreement with those obtained using the finite difference method.
