Spectrally shaped and pulse-by-pulse multiplexed multimode squeezed states of light Open
Spectral- and time-multiplexing are currently explored to generate large multipartite quantum states of light for quantum technologies. In the continuous variable approach, the deterministic generation of scalable entangled states requires…

Noise investigation of CW and mode-locked harmonic cavity nanolasers Open
We theoretically investigate the noise properties of harmonic cavity nanolasers by introducing a model of coupled equations of evolution of the modes, taking spontaneous emission into account. This model is used to predict the noise among …

Approche modale de la dynamique des peignes de fréquences et applications Open
The main focus of this manuscript is the investigation of the dynamics of optical frequency combs. Based on a spectral modal decomposition of the electric field, a full characterization of the laser dynamics is achieved by measuring the fl…

Unveiling the dynamics of optical frequency combs from phase-amplitude correlations Open
The noise dynamics of an optical frequency comb based on a mode-locked Ti-sapphire laser is analyzed in terms of noise modes. A spectrally resolved multipixel homodyne detection enables the simultaneous measurement of the amplitude and pha…
