An optical vortex is a zero of an optical field; a point of zero intensity. The term is also used to A hypergeometric-Gaussian mode (HyGG) has an optical vortex in its center. The beam, which has the form. ψ ∝ e i m ϕ e − r 2, {\displaystyle \psi  ‎Explanation - ‎Properties - ‎Creation - ‎Applications. We successfully calculated the vectorial modes of the fibre, excited the OAM states and Intensity of the vortex mode resulting from the interference pattern. Here, we propose a general strategy to design dual-modes vortex beam generator by using metasurfaces with polarization-dependent.

Probability density of orbital angular momentum mode of autofocusing Airy beam carrying power-exponent-phase vortex through weak.

The unique properties of optical vortex beams, in particular their spiral wavefront, have .. in the laser operating with a vortex mode (figure 4). for High-Resolution and Efficient Sorting of Optical Vortex Modes the orthogonality of photonic orbital angular momentum mode space. Abstract—Vector vortex beams are structured states of light that are non- separable in their polarisation and spatial mode, they are eigenmodes. vector vortex beams are optical modes with well defined spatial polarization modulation and topological vortex charge. The q-plate can naturally generate these.
