Abstract
We introduce a new type of distributed fiber strain sensor that leverages the high intensity and linewidth narrowing associated with the Brillouin lasing transition to precisely measure the Brillouin resonant frequency at discrete locations along a fiber. The system operates by exciting a series of lasing modes that experience Brillouin amplification at discrete spatial locations in a fiber. We introduce the basic operating principle and modifications enabling practical operation. Finally, we demonstrate sensing with wide dynamic range (>5 mε) and ultra-low noise (4 nε/√Hz) in 400 m of fiber with 4 m spatial resolution and a bandwidth of ~10 kHz.
