Paper Abstract

We propose a novel hollow-core slow light waveguide using high contrast grating (HCG). Light propagates in air along a path bounded by two HCG layers. A strong interaction between the light and the HCG leads to a large group index, and thus the slow light effect. Waveguide loss and group index can be optimized separately by tuning the HCG and waveguide parameters. High performance slow light is obtained with <0.1 dB/cm loss, >120 group index and >120 GHz bandwidth.
