Abstract:
A ultrasensitive fibre sensor exploring random optical parametric oscillation is proposed and experimentally verified, achieving >10 dB signal-to-noise ratio at locations beyond 25 km. It features 1-m spatial resolution and temperature/strain sensitivities of 65.8 μ (deg) C and 80.6 p(ε)/ √ Hz, leveraged from Modulation Instability and Rayleigh scattering.
