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…
