Robust Unidirectional Edge States in the Continuum in non-Topological Floquet Photonic Crystals
Hairong Huo, Yongyou Zhang, Bingsuo Zou
Robust unidirectional edge propagation is conventionally attributed to topological protection. Whether edge states in the continuum (EICs) can exhibit such robustness in non-topolo…
Statistics of tens-of-photon states scattered by optical cavity, two-level atom and Jaynes-Cummings emitter
Jia-Nan Wu, Bingsuo Zou, and Yongyou Zhang
Manipulating photon states serves as a primary requirement for various optical devices and is of high relevance for quantum information technology. Nevertheless, the fundamental th…
Exceptional points in a topological photonic system
Junhua Dong, Chang-Yin Ji, Qingmei Hu +2
Exceptional points as branch singularities describe peculiar degeneracies of non-Hermitian systems that do not obey energy conservation. This work shows that exceptional points can…
Topologically protected Fano resonance in photonic valley Hall insulators
Chang-Yin Ji, Yongyou Zhang, Bingsuo Zou +1
Rapidly developing photonics brings many interesting resonant optical phenomena, in which the Fano resonance (FR) always intrigues researchers because of its applications in optica…
Transport tuning of photonic topological edge states by optical cavities
Chang-Yin Ji, Gui-Bin Liu, Yongyou Zhang +2
Crystal-symmetry-protected photonic topological edge states (PTESs) based on air rods in conventional dielectric materials are designed as photonic topological waveguides (PTWs) co…
Excitation of exciton-polariton vortices in pillar microcavities by a Gaussian beam
A. S. Abdalla, Bingsuo Zou, Yuan Ren +2
With coupled Gross-Piteavskii equations we study excitation of exciton-polariton vortices and antivortices in a pillar microcavity by a Gaussian pump beam. The structure of vortice…
Suppression of space broadening of exciton polariton beams by Bloch oscillation effects
Xudong Duan, Bingsuo Zou, Yongyou Zhang
We theoretically study the transport of exciton polaritons under different applied photon potentials. The relation between the photon potentials and the thickness of the cavity lay…
Transmission comb of a distributed Bragg reflector induced by two surface dielectric gratings
Xiaobo Zhao, Bingsuo Zou, Yongyou Zhang
With transfer matrix theory, we study the transmission of a distributed Bragg reflector (DBR) with two dielectric gratings on top and on the bottom. Owing to the diffraction of the…
Nonlocal coupling effects on single-photon transmission in a one-dimensional waveguide interacted with a side optical cavity
Yongyou Zhang, Bingsuo Zou
The nonlocal coupling effect between a one-dimensional waveguide (1DW) and a side optical cavity (SOC) is studied. We first find the real-space Hamiltonian of the nonlocal-coupling…
