In this paper we investigate the most popular silicon waveguide structures in the form of a silicon-on-insulator (SOI) rib waveguide. Single mode and birefringence free conditions in these relatively small waveguides are discussed and the influence of the top oxide cladding stress is analyzed. Field profiles for a wide range of waveguide cross section shapes and dimensions are systematically considered. Design guidelines for this type of SOI waveguides are presented
