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…

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…
