Rydberg excitation of cold atoms inside a hollow core fiber
2017
We report on a versatile, highly controllable hybrid cold Rydberg atom fiber interface, based on laser cooled atoms transported into a hollow core Kagom\'{e} crystal fiber. Our experiments are the first to demonstrate the feasibility of exciting cold Rydberg atoms inside a hollow core fiber and we study the influence of the fiber on Rydberg electromagnetically induced transparency (EIT) signals. Using a temporally resolved detection method to distinguish between excitation and loss, we observe two different regimes of the Rydberg excitations: one EIT regime and one regime dominated by atom loss. These results are a substantial advancement towards future use of our system for quantum simulat…
Taper à fibre optique microstructurée air/slice à dispersion modifiée pour une émission large bande et accordée autour de 2 µM par mélange à quatre o…

International audience; Ce travail rapporte la conception, la fabrication et la caractérisation d'une fibre optique mircrostructurée air/silice effilée permettant une conversion de fréquence large bande par le processus de mélange à quatre ondes vers le moyen infra-rouge. Nous démontrons expérimentalement une bande de gain paramétrique de près de 100 nm. Une utilisation envisagée de ce taper réside dans le développement de sources laser femtosecondes.

Higher-order dispersion parameters management in highly nonlinear photonic crystal fibers for far-detuned frequency conversion
2022
International audience; In this communication we present results dealing with the precise management of dispersion coefficients into two highly nonlinear fiber structures (a tapered PCF and an all-solid fiber) for far-detuned frequency conversion towards 2µm.
