Figure 3 | Moiré scattering and structured radiation in twisted bilayer flat optics. a, Twisting two photonic crystal slabs rotates their reciprocal lattices and creates moiré momentum channels. b, Twist-enabled band folding and resonance imaging reveal multichannel optical coupling. c, Twisted bilayers can support spin-orbit conversion through moiré diffraction. d, Moiré momentum mixing opens controllable radiation channels from bound states in the continuum and can generate vortex emission. e, Time-domain field evolution illustrates the structured optical response enabled by twisted bilayer coupling.
