Parity-Time Symmetry in Non-Hermitian Complex Optical Media
Samit Kumar Gupta, Yi Zou, Xue-Yi Zhu +4
The explorations of the quantum-inspired symmetries in optical and photonic systems have witnessed immense research interests both fundamentally and technologically in a wide range…
Topological Flat Band and Parity-Time Symmetry in a Honeycomb Lattice of Coupled Resonant Optical Waveguides
Xue-Yi Zhu, Samit Kumar Gupta, Xiao-Chen Sun +6
Two-dimensional (2D) coupled resonant optical waveguide (CROW), exhibiting topological edge states, provides an efficient platform for designing integrated topological photonic dev…
Trapped modes with extremely high quality factor in the subwavelength ring resonator composed of dielectric nanorods
Hai-bin Lü, Xiaoping Liu
In this paper, we investigate numerically the trapped modes with near zero group velocities supported in the ring array composed of dielectric nanorods, based on a two-dimensional…
Photonic analogue of quantum spin Hall effect
Cheng He, Xiao-Chen Sun, Xiao-ping Liu +4
Symmetry-protected photonic topological insulator exhibiting robust pseudo-spin-dependent transportation, analogous to quantum spin Hall (QSH) phases and topological insulators, ar…
Optical Analogue of Quantum Spin Hall Effect in a Two-Dimensional Gyrotropic Photonic Crystal
Cheng He, Xiao-Chen Sun, Xiao-ping Liu +4
We propose an optical counterpart of the quantum spin Hall (QSH) effect in a two-dimensional photonic crystal composed of a gyrotropic medium exhibiting both gyroelectric and gyrom…
