Wireless Optical telecommunications beyond the horizon

Foundation for Research and Technology - Hellas (FORTH)


Wireless optical telecommunication systems are limited in respect to their operational range from two important factors, earth's curvature and atmospheric turbulence. The use of a new family of optical beams, Airy beams, which propagate in a parabolic trajectory and their non-diffracting properties open up new capabilities in wireless optical telecommunications. The driving idea behind the proposed research project is the following: The parabolic trajectory of Airy beams allows them to propagate in a curved trajectory with radius of curvature comparable to that of earth thus achieving optical link beyond the horizon! Furthermore, the degenerative action of atmospheric turbulence can be suppressed by their ability to self-heal. The proposed research will focus on the theoretical and experimental study of the generation and propagation of beams that propagate in a parabolic trajectory, in order to be utilized in wireless optical telecommunications between remote points that are not in direct optical contact.
