Dynamic strain sensing using Doppler-shift-immune phase-sensitive OFDR with ultra-weak reflection array and frequency-tracking
Qiang Yang, Weilin Xie, Congfan Wang +5
In distributed fiber-optic sensing based on optical frequency domain reflectometry (OFDR), Doppler frequency shifts due to the changes of disturbances during one sweep period intro…
Multi-core fiber enabled fading noise suppression in ϕ-OFDR based quantitative distributed vibration sensing
Yuxiang Feng, Weilin Xie, Yinxia Meng +7
Coherent fading has been regarded as a critical issue in phase-sensitive optical frequency domain reflectometry (ϕ-OFDR) based distributed fiber-optic sensing. Here, we report on a…
Investigation of analog signal distortion introduced by a fiber phase sensitive amplifier
Debanuj Chatterjee, Yousra Bouasria, Weilin Xie +4
We numerically simulate the distortion of an analog signal carried in a microwave photonics link containing a phase sensitive amplifier (PSA), focusing mainly on amplitude modulati…
Investigation of the noise figure in degenerate dual-pump phase sensitive amplifier using a multi-wave model
Yousra Bouasria, Debanuj Chatterjee, Weilin Xie +4
A semi-classical 7-wave model is developed to investigate the noise performances of a degenerate dual-pump phase sensitive amplifier. This approach takes into account the transfer…
Phase evolution of the direct detection noise figure of a nondegenerate fiber phase sensitive amplifier
Tarek Labidi, Ihsan Fsaifes, Weilin Xie +3
We experimentally investigate the evolution of the direct detection noise figure of a non degenerate phase sensitive amplifier based on nonlinear fiber, as a function of the relati…
Phase-sensitive amplification via coherent population oscillations in metastable helium at room temperature
J. Lugani, C. Banerjee, M-A. Maynard +5
We report our experimental results on phase-sensitive amplification (PSA) in non-degenerate signal-idler configuration using ultra-narrow coherent population oscillations in metast…
Investigation of degenerate dual-pump phase sensitive amplifier using multi-wave model
Weilin Xie, Ihsan Fsaifes, Tarek Labidi +1
Operation of a degenerate dual-pump phase sensitive amplifier (PSA) is thoroughly numerically investigated using a multi-wave model, taking into account high-order waves associated…
