Creation and dynamics of spin fluctuations in a noisy magnetic field
J. Delpy, S. Liu, P. Neveu +4
We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a stan…
Spin noise spectroscopy of optical light shifts
Joseph Delpy, Shikang Liu, Pascal Neveu +3
Light induced non-equilibrium spin noise spectroscopy is theoretically and experimentally shown to be an efficient technique to reveal the structure and the coherent effects in the…
New method for residual amplitude modulation control in fibered optical experiments
Maxime Descampeaux, Gilles Feugnet, Fabien Bretenaker
When locking the frequency of a laser to an optical cavity resonance, the residual amplitude modulation (RAM), which accompanies the phase modulation necessary to build the error s…
Imaging through fog using quadrature lock-in discrimination
Shashank Kumar, Bapan Debnath, Meena M. S. +5
We report experiments conducted in the field in the presence of fog, that were aimed at imaging under poor visibility. By means of intensity modulation at the source and two-dimens…
Generalised expression of the noise figure of phase sensitive amplifiers for an arbitrary number of modes
Yousra Bouasria, Debanuj Chatterjee, Fabienne Goldfarb +2
Phase sensitive amplifiers (PSA), contrary to usual phase insensitive amplifiers (PIA), are in principle capable to achieve noiseless amplification, i.e. exhibit a quantum-limited…
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…
