Dynamics of self-accelerating electron beams in a homogeneous magnetic field
Michael Goutsoulas, Nikolaos K. Efremidis
We examine the dynamics of electron beams that, in free space, are self-accelerating, in the presence of an additional magnetic field. We focus our attention in the case of Airy be…
Tunable self-similar Bessel-like beams of arbitrary order
Michael Goutsoulas, Domenico Bongiovanni, Denghui Li +2
We predict that Bessel-like beams of arbitrary integer order can exhibit a tunable self-similar behavior (that take an invariant form under suitable stretching transformations). Sp…
Observation of microscale nonparaxial optical bottle beams
Raluca-Sorina Penciu, Yujie Qiu, Michael Goutsoulas +5
We predict and experimentally observe three-dimensional microscale nonparaxial optical bottle beams based on the generation of a caustic surface under revolution. Such bottle beams…
Independent amplitude and trajectory/beam-width control of nonparaxial beams
Michael Goutsoulas, Raluca-Sorina Penciu, Nikolaos K. Efremidis
We show that it is possible to generate non-paraxial optical beams with pre-engineered trajectories and designed maximum amplitude along these trajectories. The independent control…
Precise amplitude, trajectory, and beam-width control of accelerating and abruptly autofocusing beams
Michael Goutsoulas, Nikolaos K. Efremidis
We show that it is possible to independently control both the trajectory and the maximum amplitude along the trajectory of a paraxial accelerating beam. This is accomplished by car…
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…
