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…
Breaking through the bandwidth barrier in distributed fiber vibration sensing by sub-Nyquist randomized sampling
Jingdong Zhang, Tao Zhu, Hua Zheng +3
The round trip time of the light pulse limits the maximum detectable frequency response range of vibration in phase-sensitive optical time domain reflectometry (ϕ-OTDR). We propose…
Modulated Pulses Based High Spatial Resolution Distributed Fiber System for Multi-Parameter Sensing
Jingdong Zhang, Tao Zhu, Huan Zhou +3
We demonstrate a hybrid distributed fiber sensing system for multi-parameter detection. The integration of phase-sensitive optical time domain reflectometry (Φ-OTDR) and Brillouin…
Experimental evidence of optical analogue of electromagnetically induced transparency in graphene
Lei Gao, Tao Zhu, Min Liu +3
We demonstrate the first experimental observation of coherent population oscillation, an optical analogue of electromagnetically induced transparency, in graphene based on phase se…
Coherence loss of partially mode-locked fiber laser
Lei Gao, Tao Zhu, Stefan Wabnitz +2
Stochastically driven nonlinear processes limit the number of amplified modes in a natural system due to competitive mode interaction, which is accompanied by loss of coherence whe…
Cross-phase modulation instability in mode-locked laser based on reduced graphene oxide
Lei Gaol, Tao Zhu, Min Liu +1
Cross-phase modulation instability (XPMI) is experimentally observed in a fiber ring cavity with net normal dispersion and mode-locked by long fiber taper. The taper is deposited w…
Vector rectangular-shape laser based on reduced graphene oxide interacting with long fiber taper
Lei Gao, Tao Zhu, Jing Zeng +2
A vector dual-wavelength rectangular-shape laser (RSL) based on a long fiber taper deposited with reduced graphene oxide is proposed, where the nonlinearity is enhanced due to larg…
