Sampling and amplification technique based on XPM-induced focusing in normally dispersive optical fibers
International audience; We theoretically and experimentally investigate an all-optical amplification and sampling technique based on a XPM process between an arbitrary signal and an intense orthogonally polarized high repetition rate sinusoidal pump wave within a normally dispersive optical fiber.
40 GHz pulse source based on cross-phase modulation-induced focusing in normally dispersive optical fibers.
We theoretically and experimentally investigate the design of a high-repetition rate source delivering well-separated optical pulses due to the nonlinear compression of a dual-frequency beat signal within a cavity-less normally dispersive fiber-based setup. This system is well described by a set of two coupled nonlinear Schrodinger equations for which the traditional normally dispersive defocusing regime is turned in a focusing temporal lens through a degenerated cross-phase modulation process (XPM). More precisely, the temporal compression of the initial beating is performed by the combined effects of normal dispersion and XPM-induced nonlinear phase shift provided by an intense beat signa…
