The waveguide invariant for a Pekeris waveguide

The Journal of the Acoustical Society of America, 2021
A closed-form waveguide invariant β for a Pekeris waveguide is derived. It is based on the modal Wentzel-Kramers-Brillouin (WKB) dispersion equation and implicit differentiation, in conjunction with the concept of the “effective boundary depth,” ΔH(θ), where θ is the propagation angle.

Grating assisted waveguide-to-waveguide couplers [PDF]

IEEE Photonics Technology Letters, 1998
A new radiation-type waveguide-to-waveguide coupler is proposed. The coupling is realized through gratings embedded on the dielectric waveguides involved. Compared to the conventional hybrid-mode coupler, this type of coupler has advantages in that the two waveguides can be quite dissimilar as well as being separated by large distances.
