Multimode vector beam synthesis and rapid modulation via interferometric methods [PDF]

AIP Advances
Optical interference techniques are widely regarded as an effective approach for generating vector beams. In this paper, we theoretically simulate the generation of multimode vector beams through the vortex beams interference. Then, in the experiment, we

Discrete Cylindrical Vector Beam Generation from an Array of Optical Fibers [PDF]

, 2009
A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed ...

Generation of terahertz vector beams using dielectric metasurfaces via spin-decoupled phase control

Nanophotonics, 2020
Cylindrical vector beams (CVBs), being a special kind of beams with spatially variant states of polarizations, are promising in photonics applications, including high-resolution imaging, plasmon excitation, optical trapping, and laser machining. Recently,

Tip-Enhanced Raman Spectroscopy with High-Order Fiber Vector Beam Excitation

Sensors, 2018
We investigated tip-enhanced Raman spectra excited by high-order fiber vector beams. Theoretical analysis shows that the high-order fiber vector beams have stronger longitudinal electric field components than linearly polarized light under tight focusing

Entangled vector vortex beams [PDF]

Physical Review A, 2016
Light beams having a vectorial field structure, or polarization, that varies over the transverse profile and a central optical singularity are called vector vortex (VV) beams and may exhibit specific properties such as focusing into "light needles" or rotation invariance.
