Non-Hermitian Interaction between Light and Photonic Time Crystal Beyond the Floquet Quasinormal Mode Approximation
Yuhang Li, Yu Zhuang, Zilong Bao +4
We report non-Hermitian mode couplings in a photonic time crystal induced by the light within its momentum bandgap. When the relative phase between the light and the photonic time…

Twisted heterobilayer photonic crystal based on stacking and selective etching of 2D materials
Qing Wang, Yuhang Li, Shaofeng Wang +3
Nanophotonic devices with moiré superlattice is currently attracting broad interest due to the unique periodicity and high efficiency control of photons. Till now, experimental inv…
