Mode propagation in planar segmented waveguides with parabolic index segments

K THYAGARAJAN, V MAHALAKSHMI, M R SHENOY

Abstract


Propagation characteristics of planar periodic segmented waveguides consisting of infinitely extended parabolic refractive index segments in the transverse direction have been analysed using the matrix formulation of Gaussian beam propagation. Modal propagation and conditions for the existence of guided mode in such a segmented waveguide have also been obtained.

Keywords


Mode propagation; segmented waveguides; waveguide stability.
