Operando monitoring of strain field distribution in lithium battery anode via ultra-high spatial resolution optical frequency domain reflectometer
Kaijun Liu, Zhijuan Zou, Guolu Yin +7
The cycling performance of lithium-ion batteries is closely related to the expansion effect of anode materials during charge and discharge processes. Studying the mechanical field…
Pump-locked microcavity Brillouin laser
Yuqin Mao, Chaoze Zhang, Ligang Huang +6
Microcavity-based microlasers are the kernel light sources for integrating photonics and optoelectronics. The traditional pump light frequency locking mainly utilizes a complex sys…
Intrinsic Spectrum Analysis of Laser Dynamics Based on Fractional Fourier Transform
Ligang Huang, Tianyi Lan, Chaoze Zhang +8
Intrinsic spectrum that results from the coupling of spontaneous emission in a laser cavity, can determine the energy concentration and coherence of lasers, which is crucial for th…
Self-adaptive single frequency laser assisted by distributed feedbacks
Fuhui Li, Ligang Huang, Laiyang Dang +7
High-coherence light sources with an ultra-narrow linewidth are of considerable research interests in numerous fields, such as laser interferometer gravitational-wave observatory,…
Extending the dynamic strain sensing rang of phase-OTDR with frequency modulation pulse and frequency interrogation
Jingdong Zhang, Haoting Wu, Jingsheng Huang +4
We propose and experimentally demonstrate a technique to extend the dynamic sensing range of phase sensitive optical time domain reflectometry system based on the frequency interro…
Long range fading free phase-sensitive reflectometry based on multi-frequency NLFM pulse
Jingdong Zhang, Hua Zheng, Tao Zhu +5
A long range phase-sensitive optical time domain reflectometer (phi-OTDR) with a multi-frequency non-linear frequency modulation (NLFM) optical pulse is proposed in this Letter. To…
Distributed fiber sparse-wideband vibration sensing by sub-Nyquist additive random sampling
Jingdong Zhang, Hua Zheng, Tao Zhu +6
The round trip time of the light pulse limits the maximum detectable vibration frequency response range of phase-sensitive optical time domain reflectometry (ϕ-OTDR). Unlike the un…
