Silica-embedded silicon photonic crystal waveguides

White, T. P.; O'Faolain, L.; Li, Juntao; Andreani, L. C.; Krauss, T. F.


We report on the fabrication and characterization of silicon photonic crystal waveguides completely embedded in silica. These waveguides offer a robust alternative to air-membranes and are fully compatible with monolithic integration. Despite the reduced refractive index contrast compared to the air-membranes, these waveguides offer a considerable operating range of ≈10 nm in the 1550 nm window. While the reduced index contrast weakens the perturbations due to surface roughness, we measure...[Show more]
