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.

Cross-phase modulation effects in normal dispersive fibers and their applications
In this Ph.D., physical effects arising from cross-phase modulation between twoorthogonally polarized signals propagating in normal dispersion fibers arestudied and some of their applications investigated.First, a 40-GHz pulse generator is designed by sending two orthogonallypolarized out-of-phase sinusoidal waves in a normally dispersive optical fiber.A large power imbalance between the two waves induces a periodic phasepotential for the weak replica which turns the normal dispersive defocusingregime into a focusing dynamics, thus compressing the sinusoidal wave intoshort and well-separated pulses.A signal sampler and magnifier was then designed using the same principle,sending a high powe…
