Abstract
We have analyzed the linear propagation characteristics of planar peri odic segmented waveguides with infinitely extended parabolic refractiv e-index segments in the transverse direction, using the matrix formula tion of Gaussian beam propagation. Modal propagation and the variation of effective index as a function of duty cycle and the period of segm entation have been studied. Conditions for the existence of guided mod es in such a segmented waveguide are presented.
