Engineering the Light along its Axis of Propagation

Presented by Professor Mo Mojahedi, Department of Electrical & Computer Engineering, University of Toronto

Bessel Beams belong to a class of wave known as the Localized Wave, which can resist diffraction and exhibit self-healing behavior upon scattering from objects. In this talk, I will show that in addition to the aforementioned known properties, it is possible to control and modify (i.e. engineer), almost at will, the Bessel Beam's intensity (value and pattern), its orbital angular momentum (magnitude and sign), its polarization (horizontal, vertical, or radial), and/or its wavelength along the beam's axis of propagation. Such an unprecedented control can be performed for a single parameter of the beam (e.g. intensity, orbital angular momentum, polarization, and wavelength) or for a combination of these parameters. Time permitting; some application of this novel approach will be also discussed.
