Self-sweeping ytterbium-doped fiber laser based on a fiber saturable absorber
Zengrun Wen, Kaile Wang, Baole Lu +2
Generally speaking, the self-sweeping effect relies on the dynamical grating formed in a gain fiber. Here, the normal self-sweeping was generated in a pump-free ytterbium-doped fib…
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…
Broadband laser polarization control with aligned carbon nanotubes
He Yang, Bo Fua, Diao Lia +12
We introduce a simple approach to fabricate aligned carbon nanotube (ACNT) device for broadband polarization control in fiber laser systems. The ACNT device was fabricated by pulli…
