We experimentally demonstrate optical parametric chirped pulse amplification for the first time (to our knowledge) in a completely integrated all-fiber optical system. A single chirped fiber Bragg grating, achieving both the stretching and compression stages, is combined with a cw-pumped fiber optical parametric amplifier. As a proof of principle, we demonstrate the amplification of picosecond Fourier-transform-limited pulses at 1550nm.

    • "Fiber optical parametric chirped pulse amplification (FOPCPA) has recently been the focus of studies as a promising amplification scheme for pico-and femto-second pulses in optical fibers [1] [2] [3]. Since parametric amplification is an ultrafast process with gain strongly dependent on the input signal power [4], the output of an FOPCPA depends on the temporal profile of the input chirped signal, an effect that is revealed in the amplified signal after recompression.

    ABSTRACT: Fiber optical parametric chirped pulse amplification is experimentally compared for different chirped pulses in the picosecond regime. The amplified chirped pulses show distortion appearing as pedestals after recompression when the amplifier is operated in saturation.

    ABSTRACT: We experimentally demonstrate, for the first time to the best of our knowledge, the use of optical fiber for optical parametric chirped pulse amplification to amplify subpicosecond pulses. We use this system to amplify a subpicosecond signal at 1595 nm generated by a fiber-optical parametric oscillator. The 750-fs signal from the oscillator output is stretched to 40 ps, amplified by an all-fiber optical parametric amplifier and then compressed to 808 fs. The peak power of the signal is amplified from 93 mW to 10 W.

    ABSTRACT: In this paper, an optical parametric amplifier and wavelength converter in an all-fiber optical configuration is experimentally demonstrated for photonic applications in the 1 μm band. This is achieved by using a microstructured fiber which provides anomalous dispersion at 1 μm and an LiNbO<sub>3</sub> electro-optic intensity modulator specially designed at this operating wavelength for generating pump pulses. A gain of greater than 30 dB together with highly efficient wavelength conversion is obtained at 1053 nm. The gain bandwidth and gain-power efficiency are also investigated. Experimental results agree well with the theory of parametric amplification including Raman scattering.
