Optimised photonic crystal waveguide for chiral light-matter interactions

TL;DR

This paper introduces optimized photonic crystal waveguides that significantly enhance chiral light-matter interactions by increasing the local density of optical states, enabling better control of light at the quantum level.

Contribution

The authors design a slow-light photonic crystal waveguide with an 8.6-fold improvement in local density of optical states at a chiral point, surpassing previous designs.

Findings

8.6 times increase in local density of optical states

Enhanced control of chiral light-matter interactions

Potential applications in quantum photonics

Abstract

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