We demonstrate a photonic analog of twisted bilayer graphene that has ultra-flat photonic bands and exhibits extreme slow light behavior. Our twisted bilayer photonic device, which has an operating wavelength in C-band of the telecom window, uses two crystalline silicon photonic crystal slabs ...
In quantum mechanics, wavefront dislocations have been predicted in connection to the Aharonov–Bohm effect8,9, and they have been observed recently in the electron density of graphene as a manifestation of the wave-function Berry phase10,11. In parallel, topology also spread in condensed matter...

The field of topological photonic crystals has attracted growing interest since the inception of optical analog of quantum Hall effect proposed in 2008. Photonic band structures embraced topological phases of matter, have spawned a novel platform for studying topological phase transitions and designing top...
