Twisted Bilayer Photonic Crystals
Exploring light manipulation in moiré photonic lattices.
This project explores the fascinating optical properties of twisted bilayer photonic crystal slabs. By stacking two photonic crystal slabs and rotating them relative to each other, we create a moiré pattern that significantly alters the flow of light.
Key Highlights
- Tunable Resonance: We demonstrated how the twist angle can be used to tune the frequency of guided resonances.
- Flat Bands: Moiré physics leads to the emergence of extremely flat bands, which can enhance light-matter interaction.
- Inverse Design: Using machine learning and automatic differentiation to design these complex structures.
