Engineering of orbital angular momentum supermodes in coupled optical waveguides
A. Turpin, G. Pelegrí, J. Polo +2
In this work we demonstrate the existence of orbital angular momentum (OAM) bright and dark supermodes in a three-evanescently coupled cylindrical waveguides system. Bright and dar…
Polarization tailored novel vector beams based on conical refraction
A. Turpin, Yu. V. Loiko, A. Peinado +4
Coherent vector beams with involved states of polarization (SOP) are widespread in the literature, having applications in laser processing, super-resolution imaging and particle tr…
Super-Gaussian conical refraction beam
A. Turpin, Yu. V. Loiko, T. K. Kalkandkiev +2
We demonstrate the transformation of Gaussian input beams into super-Gaussian beams with a quasi flat-top transverse profile by means of the conical refraction phenomenon by adjust…
Optical vault: reconfigurable bottle beam by conically refracted light
A. Turpin, V. Shvedov, C. Hnatovsy +3
We employ conical refraction of light in a biaxial crystal to create an optical bottle for trapping and manipulation of particles. We show that by just varying the polarization of…
