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 ondes dégénérées

Ahmedou, Sidi-Ely Walter, Guillaume Dauliat, Romain

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...

Fabrication and characterization of tapered photonic crystal fiber for broadband 2 µm: four-wave mixing-based fibered OPCPA

Ahmedou, Sidi-Ely Walter, Guillaume Herbuvaux, Jules

We present the simulation, fabrication, and characterization of large area microstructured fiber tapers which enables broadband phasematching conditions of the four wave-mixing process. These silica-based tapers are intended to serve as a nonlinear gain medium for intense and high average power Fiber Optical Parametric Chirped Pulse Amplifier...

Higher-order dispersion parameters management in highly nonlinear photonic crystal fibers for far-detuned frequency conversion

Ahmedou, Sidi-Ely Dauliat, Romain Leconte, Baptiste

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.
