Figure 2 | “Optical fibre on a chip". Cross-sectional scanning electron microscope image of a thermally reflowed germano-silicate waveguide. Surface tension reshapes the etched ridge into a smooth, rounded profile, reducing scattering loss from sidewall roughness and helping integrated microresonators reach ultrahigh Q.
