Abstract
We present slow-light photonic crystal waveguide designs that provide a ×8.6 improvement of the local density of optical states at a fully chiral point over previous designs.

Chirality couples the spin direction of electrons to the travel direction of light. This chiral light–matter interaction is at its most useful when the chirality reaches 100% at a singular position known as a C-point
Summary
Chirality of light in (nano-)photonic structures is proving to be a valuable resource [1,2,3]. Abstract We present slow-light photonic crystal waveguide designs that provide a ×8.6 improvement of the local density of optical states at a fully chiral point over previous designs. Photonic crystal waveguides (PhCWGs) present several unique benefits to realising chirality-direction coupling.
