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…
Ultra-low noise dual-frequency VECSEL at telecom wavelength using fully correlated pumping
Hui Liu, Grégory Gredat, Syamsundar De +7
An ultra-low intensity and beatnote phase noise dual-frequency vertical-external-cavity surface-emitting laser is built at telecom wavelength. The pump laser is realized by polariz…
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…
Fully-correlated pumping for dual-frequency VECSELs dedicated to cesium CPT clocks
G. Gredat, D. Chatterjee, G. Baili +4
We report a fully-correlated multi-mode pumping architecture optimized for dramatic noise reduction of a class-A dual-frequency Vertical External Cavity Surface Emitting Laser (VEC…
Excess noise factor in non-Hermitian mode-locked lasers
Oriane Lelièvre, Khadija Abensar, Ghaya Baili +3
We predict and observe the appearance of an excess noise factor due to the non-Hermiticity of the modes of two actively harmonically mode-locked lasers. The non uniform distributio…
Phase Noise of the Radio Frequency (RF) Beatnote Generated by a Dual-Frequency VECSEL
Syamsundar De, Abdelkrim El Amili, Ihsan Fsaifes +6
We analyze, both theoretically and experimentally, the phase noise of the radio frequency (RF) beatnote generated by optical mixing of two orthogonally polarized modes in an optica…
