Twist-induced orbital chirality in a photonic laser

KFKristina FrizyukKarlsruhe Institute of Technology CACostantino De Angelis

Key Points

This research aims to explore how twist-induced orbital chirality affects laser emission.
Investigated the combination of two achiral photonic membranes into a twisted bilayer.
Examined the effects of mirror symmetry breaking on collective modes.
Analyzed non-Hermitian coupling between modes.
Mirror symmetry was successfully broken by twisting the bilayer membranes.
Chiral laser emission was observed due to the induced orbital chirality.

Abstract

The combination of two achiral photonic membranes into a twisted bilayer breaks mirror symmetry and induces non-Hermitian coupling between counter-rotating collective modes, making laser emission chiral.
