Observation of compact edge states in laser-written graphene photonic lattices

Researchers engineer robust, compact edge states in laser-fabricated graphene-like photonic lattices by inducing topological protection through synthetic flux. These perfectly localized edge modes are highly stable, resistant to fabrication errors and input fluctuations. This offers a route to multi-flatband materials for low-energy electronics.
