How many supercells are required to achieve unconventional light confinement effects in moiré photonic lattices?
Chirine Saadi, Hai Son Nguyen, Sébastien Cueff +3
Moiré structures are receiving increasing attention in nanophotonics as they support intriguing optical phenomena. In the so-called "magic configuration", one-dimensional moirés gi…
