We present the principles of variable pure polarization rotators based on the accumulation of a geometric phase that is obtained by coiling a beam of light via discrete reflections. They consist of two pseudo rotators in series. By changing the angle

A higher-order Poincare sphere and Stokes parameter representation of the higher-order states of polarization of vector vortex beams that includes radial and azimuthal polarized cylindrical vector beams is presented. The higher-order Poincare sphere

We present a geometric phase arising from transformations along the surface of a Poincare sphere representation for cylindrical vector beams. Cylindrical vector beams are expressed as the superposition of orthogonal circular polarized Laguerre-Gaussi

A method for the generation of cylindrical vector beams based on the design of a multicore optical fiber is presented. This design consists of N elliptical cores symmetrically arranged in a circular array about the fiber axis, where the orientation o

A hybrid vector polarization beam with a donut like intensity profile is produced at the output of a spun elliptical core optical fiber by coupling an off-axis TEM 00 laser mode at the input. The local polarization states of the fiber output are anal

The propagation of a hybrid vector polarization beam is experimentally investigated in an uniaxial birefringent quartz crystal. The hybrid beam can be expressed as a superposition of two orthogonal linearly polarized Laguerre-Gaussian modes of opposi

Optical Airy beams have gained significant attention due to their parabolic trajectory, accelerating and nondiffractive behavior. The phase velocity of the Airy solution to the paraxial wave equation is described showing a unique behavior. The veloci

Two Poincare spheres for cylindrical vector beams are described. The two spheres share circularly polarized LG modes as their eigenstates, i.e poles. A geometric phase is shown from evolution along the surface of these spheres.

Coherent optical vortices are generated from ultrashort 6.4 fs pulses. Our results demonstrate angular dispersion compensation of ultrashort 6.4 fs Laguerre-Gaussian (LG) pulses as well as what is believed to be the first direct autocorrelation measu
