Impact of noise on nonlinear-exceptional-point-based sensors
Kai Bai, Chen Lin, Meng Xiao
Nonlinear exceptional points (NEPs), a new type of spectral singularity in nonlinear non-Hermitian systems, are expected to address the noise divergence issue encountered at linear…
Topological phase transition induced by modulating unit cells in photonic Lieb lattice
Zhi-Kang Xiong, Y. Liu, Xiying Fan +1
Topological photonics was embarked from realizing the first-order chiral state in gyromagnetic media, but its higher-order states were mostly studied in dielectric lattice instead.…
Plasmonic Nanoparticle-in-nanoslit Antenna as Independently Tunable Dual-Resonant Systems for Efficient Frequency Upconversion
Huatian Hu, Zhiwei Hu, Christophe Galland +1
Dual-band plasmonic nanoantennas, exhibiting two widely separated user-defined resonances, are fundamental building blocks for the investigation and optimization of plasmon-enhance…
Topological Degeneracy Induced by Twisting
Han Peng, Qiang Wang, Meng Xiao +3
In recent years, twisting has emerged as a new degree of freedom that plays an increasingly important role in Bloch bands of various physical systems. However, there is currently a…
Manipulating terahertz phonon-polariton in the ultrastrong coupling regime with bound states in the continuum
Jiaxing Yang, Liyu Zhang, Kai Wang +7
The strong coupling between photons and phonons in polar materials gives rise to phonon-polaritons that encapsulate a wealth of physical information, offering crucial tools for the…
Nonlinear Non-Hermitian Skin Effect and Skin Solitons in Temporal Photonic Feedforward Lattices
Shulin Wang, Bing Wang, Chenyu Liu +5
Here we report the experimental demonstration of the nonlinear non-Hermitian skin effect (NHSE) in an effective Kerr nonlinear temporal photonic lattice, where the high-power requi…
