Abstract
Fiber optical parametric amplifiers (FOPAs) have attracted considerable attention during the last decade because of their
broad bandwidth, high gain and wavelength-flexibility. In comparison to cumbersome bulky systems, they bring the
advantages of all-fiber systems, i.e. reliability, long-term stability and compactness. FOPAs rely on the third-order
susceptibility and are characterized by a quasi-instantaneous nonlinear response that involves pump, signal and idler
waves. Chirped pulse amplification (CPA) allows to get a high energy amplification and its realization in FOPAs would
increase the overall performances of these amplifiers. Such an experimental demonstration has never been reported in the
past. In this work, we show for the first time the experimental feasibility of fiber-based optical parametric chirped pulse
amplification (FOPCPA) with an all-fibered setup. The stretching/compression stages are realized with a single linearly
chirped fiber Bragg grating (LCFBG) used in both directions while the amplification is performed in a CW-pumped
FOPA that uses 500 meters of highly nonlinear fiber (HNLF). Fourier transform limited optical pulses at 1550 nm are
stretched from 6 ps to 70 ps and then amplified by 22 dB without any spectral or temporal distortions. Experiments are
confirmed by simulations carried out by numerical integration of the nonlinear Schrödinger equation with parameters
matching those of the experimental setup. For simplicity, this first experimental demonstration is realized in the
telecommunication window. By using photonic crystal fibers, one can move the working wavelength around 1 μm.
