Spatiotemporal diffraction-free pulsed beams in free-space of the Airy and Bessel type
Nikolaos K. Efremidis
We investigate the dynamics of spatiotemporal optical waves with one transverse dimension that are obtained as the intersections of the dispersion cone with a plane. We show that,…
Cross-phase modulation mediated pulse control with Airy pulses in optical fibers
Michael Goutsoulas, Vassilis Paltoglou, Nikolaos K. Efremidis
We show that the velocity and thus the frequency of a signal pulse can be adjusted by the use of a control Airy pulse. In particular, we utilize a nonlinear Airy pulse which, via c…
Exact bidirectional X-wave solutions in fiber Bragg gratings
Nikolaos K. Efremidis, Nicholas S. Nye, Demetrios N. Christodoulides
We find exact solutions describing bidirectional pulses propagating in fiber Bragg gratings. They are derived by solving the coupled-mode theory equations and are expressed in term…
