Distortionless pulse transmission in valley photonic crystal slab waveguide
Fu-Long Shi, Yuan Cao, Xiao-Dong Chen +4
Valley photonic crystal is one type of photonic topological insulator, whose realization only needs P-symmetry breaking. The domain wall between two valley-contrasting photonic cry…
Frequency-dependent topological phases and photonic detouring in valley photonic crystals
Guo-Jing Tang, Xiao-Dong Chen, Fu-Long Shi +3
Here, the frequency degree of freedom is introduced into valley photonic crystals with dual band gaps. Based on the high-order plane wave expansion model, we derive an effective Ha…
Direct observation of corner states in second-order topological photonic crystal slabs
Xiao-Dong Chen, Wei-Min Deng, Fu-Long Shi +3
Recently, higher-order topological phases that do not obey the usual bulk-edge correspondence principle have been introduced in electronic insulators and brought into classical sys…
Edge states in self-complementary checkerboard photonic crystals: Zak phase, surface impedance and experimental verification
Xiao-Dong Chen, Ding Zhao, Xiao-Sheng Zhu +5
Edge states of photonic crystals have attracted much attention for the potential applications such as high transmission waveguide bends, spin dependent splitters and one-way photon…
Valley-contrasting orbital angular momentum in photonic valley crystals
Xiaodong Chen, Min Chen, Jianwen Dong
Valley, as a degree of freedom, has been exploited to realize valley-selective Hall transport and circular dichroism in two-dimensional layered materials. On the other hand, orbita…
