Symmetry-Encoded Multiplexed Lasing Enabled by Twisted Moiré Photonic Coupling
Multifunctional lasers are critical for enhancing system versatility and information capacity. However, realizing multiplexed lasing across multiple degrees of freedom requires unconventional physical mechanisms. Here, we demonstrate how twisted moiré photonic superlattices can enable symmetry-encoded, multiplexed lasing characteristics. By constructing moiré lasers using perovskite nanocrystals, we demonstrate polarization-vortex beams from symmetry-protected bound states in the continuum (BICs) and linearly polarized beams from symmetry-broken radiative modes simultaneously at distinct spatial channels. We reveal that although the superlattice symmetry generates multiple BICs from photonic band folding, the asymmetric interference between the superlattice and sublattice modes turns the BICs at moiré-Γ points into radiative modes, which enables symmetry-broken polarization characters. Using twist angles as a tuning approach, we achieved independent modulation of the laser emission directionality, with the multichannel laser polarizations remaining invariant. Our discoveries of moiré-coupling-induced, multiplexed light manipulation offer opportunities for multichannel visible-light communication, holographic displays, and augmented reality.
