Low-loss slow light in high contrast grating hollow-core waveguides

A chip-scale hollow-core waveguide using high-contrast grating yields slow light with a group velocity <0.02c and loss as low as 0.2dB/cm over 50GHz bandwidth. Loss and group velocity are independently optimized for the first time.
