Terahertz vortex beam generation by infrared vector beam rectification

Journal of the Optical Society of America B: Optical Physics, 2019
International audienceWe report on the conversion of an infrared vector beam into terahertz vortex beams using a 110-cut ZnTe cubic crystal. First, we provide a theoretical analysis demonstrating how an infrared vector beam with the azimuthal order can ...

Switchable vector vortex beam generation using an optical fiber

Optics Communications, 2010
We present our experimental results on directly transforming a circular-polarized Gaussian beam into linear-polarized vector vortex beams using a two-mode fiber and demonstrate switching between the different 0th-order vector vortex modes excited and ...

Continuously Variable Topological Charge of a Vector Vortex Beam Generated by an Integrated Metasurface

We propose and numerically verify a new method for generating a vector vortex beam, in which the twist of the wavefront varies continuously along the beam axis, offering potential benefits for distance ...
