Optical Lattices with Higher-order Exceptional Points by Non-Hermitian Coupling
Xingping Zhou, Samit Kumar Gupta, Zhong Huang +5
Exceptional points (EPs) are degeneracies in open wave systems with coalescence of at least two energy levels and their corresponding eigenstates. In higher dimensions, more comple…
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…
