Topology of Photonic Time Crystals under Complex Refractive Index Modulation
Huili Lin, Zhaohui Dong, Xianfeng Chen +1
Photonic time crystals, constructed by periodic modulation of electromagnetic parameters in time, hold unique topological properties. Here, we explore permittivity and conductivity…
Probing Bulk Band Topology from Time Boundary Effect in Synthetic Dimension
Huisheng Xu, Zhaohui Dong, Luqi Yuan +1
An incident wave at a temporal interface, created by an abrupt change in system parameters, generates time-refracted and time-reflected waves. We find topological characteristics a…
A comprehensive review on developments of synthetic dimensions
Danying Yu, Wange Song, Luojia Wang +14
The concept of synthetic dimensions has emerged as a powerful framework in photonics and atomic physics, enabling the exploration of high-dimensional physics beyond conventional sp…
Extreme narrow band in Moiré Photonic time crystal
Zhaohui Dong, Xianfeng Chen, Luqi Yuan
The Moiré superlattice has attracted growing interest in the electromagnetic and optical communities. Here, we extend this concept to time-varying photonic systems by superposing t…
Controlling quasi-parametric amplifications: From multiple PT-symmetry phase transitions to non-Hermitian sensing
Xiaoxiong Wu, Kai Bai, Penghong Yu +7
Quasi-parametric amplification (QPA) is a nonlinear interaction in which the idler wave is depleted through some loss mechanism. QPA plays an important role in signal amplification…
