Analysis of the tapered waveguide
Belghoraf, A. (1984) Analysis of the tapered waveguide. PhD thesis, University of Nottingham.
This thesis describes analytical and numerical investigations of tapered waveguide problems, for integrated optics applications. A plane wave spectral analysis, models the propagation process of the tapered waveguide and introduces the concept of an Intrinsic spectral Integral, which turns out to be in good agreement with calculations in terms of Adiabatic modes. This allows us to extend the Intrinsic mode concept beyond the singularity where the Adiabatic mode concept breaks down.
