We report a low-loss, hybrid silicon waveguide geometry consisting of straight rib sections
with a propagation loss of 0.27 +- 0.012 dB/cm and compact photonic wire bends. The rib and wire
waveguides are both single mode and connected through a short double-etched linear taper section.
To reduce bend losses, circular bends were combined with variable adiabatic semi-natural spline
shapes with only a limited footprint penalty.
