Abstract
A silicon rib waveguide device includes a mode filter section serially connected to a curved rib section. The curved section has a width large enough to support multimode transmission while the filter section has a straight waveguide of smaller rib width supporting only single mode transmission. A tapered section connects the curved section to the straight section and an outwardly tapered waveguide is connected to the opposite end of the straight section.
