Angularly accelerating optical beams
Abstract
Structured light has recently emerged as a topic of wide interest in optics. In its more general description Structured Light refers to the controlled modulation of an optical light beam in order to engineer its properties along propagation. By modulating the phase, the amplitude, and the polarization of a light we can control the intensity, phase and polarization distribution along propagation. This thesis is focused on the theoretical study of light beams that twist as they propagate. By introducing novel design approaches we have introduced a new family of structured light, referred to as Tornado Waves (ToWs), that abruptly autofocus while twisting in an accelerating fashion. Using numerical simulations, we have demonstrated that light structures with features that twist and shrink with trajectories resembling the shape of a Tornado can be generated by beams that carry orbital angular momentum (OAM). Our findings show that Tornado waves can exhibit angular acceleration, a measure o ...
