Abstract: A new waveguide structure with periodycilly segmented cover and substrate regions and a uniform film region is proposed.This complementary segmented waveguide is analysed in terms of the effective index and the spot size of the guided mode,by expressing the propagated fild as a linear combination of the local normal mode of the corresponding uniform slab waveguides in different propagation regine.The results match very well with those obtained using the equivalent waveguide model.The propagation loss of the mode of the proposed structure is calculated using a coupled mode approach, and the results are similar to those of a normal segmented waveguide.This waveguide structure should prove useful in the realization of novel segmented waveguide devices.
