Article Synopsis
- Identifying the handedness of chiral materials is a challenging task in biochemistry, but nanophotonic structures can enhance weak chiroptical responses to aid this detection.
- This study looks into how silicon nanoparticles interact with a dielectric waveguide to sense the handedness of chiral substances by inducing polarization rotation in the wavefields.
- The research provides theoretical and numerical evidence for different configurations that enable detecting left- or right-handed particles based on noticeable transmission differences.
Photonic crystals are known for their band-gap structures. Due to their band-gaps, they can act as filters in both temporal and spatial domains. However, in most cases, due to their physical symmetry, their angular responses are symmetrical.

Here, we present a waveguide-based method to measure chirality and distinguish the enantiomers of molecules. A bi-isotropic core in an optical waveguide lifts the degeneracy of modes in a cylindrically symmetric structure.
