WebMode coupling in optical waveguide horns is described in detail. Analytic approximations for the coupling constant and phase difference are derived. For a parabolic-shaped horn an expression for the power transferred out of the lowest order mode is obtained, which demonstrates that long structures will be needed to maintain adiabatic operation. WebWe propose parabolic‐shaped coupling horns to provide adiabatic transition regions between wide‐ and narrow‐channel optical waveguides. The parabolic shape is shown to derive from a simple ray model of channel propagation and is consistent with diffraction theory in the wide‐channel limit. An approximate mode dispersion theory is used to …
