As one of the cutting-edge research areas in modern physics, space-based gravitational wave detection aims at capturing gravitational wave signals in the mHz frequency band. A key technological ...

Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...

Carrying torrents of data between internet hubs, and connecting servers, storage elements, and switches inside data centers, optical fiber communication is the backbone on which the digital world is ...

We present a long-range fiber-optic environmental deformation sensor based on active phase noise cancellation (PNC) in metrological frequency dissemination. PNC sensing exploits recordings of a ...
