The generation and manipulation of optical vortices are of fundamental importance in a
variety of promising applications. Here, we develop a nonlinear optical paradigm to …

Interference of optical beams with optical vortices is often encountered in singular optics.
Since interferometry makes the phase observable by intensity measurement, it brings out a …

Speckle metrology is a powerful tool in the measurement of wavelength and spectra.
Recently, speckle produced by multiple reflections inside an integrating sphere has been …

In this work we investigate the structure of nondiffracting speckle fields, both experimentally
and theoretically. We are able to produce very good agreement between the experimentally …

We study the properties of the Fraunhofer diffraction patterns produced by Gaussian beams
crossing spiral phase plates. We show, both analytically and numerically, that off-axis …

The internal scanning method is specific for the optical vortex microscope. It allows to move
the vortex point inside the focused vortex beam with nanometer resolution while the whole …

Anomalous diffusion of different particlelike entities, the deviation from typical Brownian
motion, is ubiquitous in complex physical and biological systems. While optical vortices …
