In this work, we present the experimental results of a direct detection π-OTDR based distributed acoustic sensor system. The system uses two cascaded acousto-optic modulators in order to generate optical pulses with very high extinction ratio and du

In this manuscript, we experimentally demonstrate a parity-time-symmetric optoelectronic oscillator (OEO) with polarization multiplexed channels. We obtained a microwave single-mode oscillation at 9.5 GHz with phase noise values of −116.2 and −12

We demonstrate the performance of dual-pulse φ-OTDR system at nearby and far-away distances, i.e. at 1.2 km and 49.1 km, in detecting and linearly retrieving the acoustic signal with proper dual-pulse probe lengths.
