Abstract :
An estimate of roughness scattering into substrate radiation modes of semiconductor rib waveguides manufactured from III-V compounds is obtained. A guided mode is supposed to be incident upon a corrugated section of the rib sidewall. It is found that scattering into substrate radiation modes considerably exceeds that into slab modes (i.e. surface waves)
