Imaginary coupling induced Dirac points and group velocity control in non-reciprocal Hermitian Lattice
Yuandan Wang, Junhao Yang, Yu Dang +3
We propose a mechanism to achieve the group velocity control of bifurcation light via an imaginary coupling effect in the non-reciprocal lattice. The physical model is composed of…
Anti-parity-time topologically undefined state
Haohao Wang, Kaiwen Ji, Yuandan Wang +6
We constructed an anti-parity-time-symmetric photonic lattice by using perturbations. The results show the topological state will appear when the waveguide coupling constants $κ_1<…
Anomalous reflection at the interface of binary synthetic photonic lattices
Zhiqing Zhang, Yanan Dai, Zengrun Wen +5
We construct a binary synthetic photonic lattice theoretically with an effective magnetic field by projecting two fiber loops' light intensity and adjusting the phase distribution…
PT-symmetric topological near-zero interface state
Zhenjuan Liu, Kaiwen Ji, Haohao Wang +6
Photonic systems with parity-time (PT) symmetry and topology are attracting considerable attentions. In this work, topological near-zero edge states are studied in PT-symmetric pho…
Narrow bandwidth Q-switched Erbium-doped fiber laser based on dynamic saturable absorption filtering effect
Zengrun Wen, Kaile Wang, Shuangcheng Chen +3
We proposed a narrow spectral bandwidth Erbium-doped fiber (EDF) laser Q-switched by a homemade saturable dynamic induced grating (SDIG) which is introduced via reforming the struc…
Discretized optical dynamics in one-dimensionally synthetic photonic lattice
Zengrun Wen, Kaile Wang, Baole Lu +3
Synthetic photonic lattice with temporally controlled potentials is a versatile platform for realizing wave dynamics associated with physical areas of optics and quantum physics. H…
Synthetic topological insulator with periodically modulated effective gauge fields
Zengrun Wen, Baole Lu, Kaiwen Ji +4
We study both theoretically and numerically the topological edge states in synthetic photonic lattice with finitely periodic gauge potentials. The effective gauge fields are implem…
