Abstract |
Recently, Airy beams, a new kind of non-spreading optical beams where the
amplitude distribution is described by an Airy function, have been introduced.
In contrast to other non-spreading optical waves the Airy distribution is the
only dispersion-free solution in one dimension. Likewise, Airy beams are also
referred to as “accelerating” since they propagate in a curved trajectory, like
that of a projectile moving under the action of gravity. Furthermore, they
are able to self-heal and bypass obstacles. These novel properties make them
exciting for applications.
In this thesis we numerically study the propagation dynamics of 1D Airy
beams. We compare our results with analytic or empirical solutions that have
been presented in the bibliography. Likewise, by varying the initial conditions
we demonstrate the ballistic dynamics of the Airy beam trajectory and by applying obstacles we study their self-healing properties. Finally, we study the
autofocusing character of a complex wave that is comprised by two counterpropagating Airy beams and demonstrate the Janus wave signature by focusing such
waves using a lens.
