We experimentally characterize the properties of an element that generates a doughnutlike point-spread function by converting the linearly polarized incident field to radially or azimuthally polarized light utilizing space-variant inhomogeneous medium (SVIM) form-birefringent subwavelength structures. To fabricate the high-aspect-ratio SVIM structures, we developed a chemically assisted ion-bea...

We demonstrate that anisotropy of Fresnel diffraction in a birefringent medium can be quantitatively characterized by planar tensor. Eigenvectors the tensor correspond to directions minimum and maximum beam divergence. Zero eigenvalues exist for fast eigenmode near optic axis biaxial crystals autocollimated propagation. Applications are demonstrated analysis noncritical phase matching acousto-o...

The random intensity distribution observed due to the propagation of a coherent beam light through scattering medium is known as speckle pattern. interaction speckles with birefringent crystal, here, YVO4 results in e-ray and o-ray speckles. It that experience an angular shift rotation crystal depends on angle crystal. also found rate different for speckles, independent topological charge incid...

We describe the evolution of a paraxial electromagnetic wave characterizing by a non-uniform polarization distribution with singularities and propagating in a weakly anisotropic medium. Our approach is based on the Stokes vector evolution equation applied to a non-uniform initial polarization field. In the case of a homogeneous medium, this equation is integrated analytically. This yields a 3-d...

We report the experimental observation of temporal vector soliton propagation and collision in a linearly birefringent optical fiber. To the best of the authors' knowledge, this is both the first demonstration of temporal vector solitons with two mutually incoherent component fields, and of vector soliton collisions in a Kerr nonlinear medium. Collisions are characterized by an intensity redist...

We investigate theoretically changes in the spectrum of polychromatic light scattered by a disordered, birefringent medium. We derive an expression for the spectrum of scattered light for ordinary and extraordinary incident waves within the accuracy of the first Born approximation. Using this result, we analyze the changes in the spectrum of light due to the combined action of disorder and anis...

Using a general model to schematize polarimetric and interferometric measurements, we derive the dependence of the output signal on the input state of polarization. We show that in any birefringent medium, in addition to the eigenvectors that maximize the interferometric phase signal, there exist dual vectors that maximize the amplitude of the polarimetric signal. The dual vectors lie on the ma...

We consider a topological Floquet insulator realized as honeycomb array of helical waveguides imprinted in weakly birefringent medium. The system accounts for four-wave mixing occurring at series resonances arising due to phase matching. Under these resonant conditions, the sustains stable linearly polarized and metastable elliptically two-component edge solitons. Coupled nonlinear equations de...

We describe the properties of specific non-reflecting birefringent left-handed metamaterials and demonstrate a birefringent perfect lens for vectorial fields. We predict that, in a sharp contrast to the concept of a conventional perfect lens realized at = μ = −1 (where is the dielectric permittivity and μ is the magnetic permeability), the birefringent left-handed slab possesses the property of...
