Bound States in the Continuum in Bilayer Photonic Crystal with TE-TM Cross-Coupling
Hong-Fei Wang, Samit Kumar Gupta, Xue-Yi Zhu +3
Bound states in the continuum (BICs) in photonic crystals represent the unique solutions of wave equations possessing an infinite quality-factor. We design a type of bilayer photon…
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…
