The relative scattering losses due to rough rib sidewalls in GaAs/AsGaAs single and double heterostructure rib waveguides are investigated theoretically. The authors find that double heterostructures exhibit at least as much scattering loss as single heterostructures, provided that such comparisons are made among structures with comparable bend performance.
