Abstract
<p indent="0mm">The introduction of topology in photonic systems has attracted considerable attention not only for the elaborate molding of light but also for its practical applications in novel photonic devices. Recently, Xiao-Dong Chen, Jian-Wen Dong, et al. from Sun Yat-sen University proposed the polarization-valley Hall effect of light in a 2D triangular-lattice photonic crystal (PC). This work proposed an approach to apply the polarization degree of freedom (DoF) in 2D valley Hall PCs.
