Single atom edge-like states via quantum interference
G. Pelegrí, J. Polo, A. Turpin +3
We demonstrate how quantum interference may lead to the appearance of robust edge-like states of a single ultracold atom in a two-dimensional optical ribbon. We show that these sta…
On the dual-cone nature of the conical refraction phenomenon
Alex Turpin, Yury V. Loiko, Todor K. Kalkandjiev +2
In conical refraction (CR), a focused Gaussian input beam passing through a biaxial crystal and parallel to one of the optic axes is transformed into a pair of concentric bright ri…
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…
Blue-detuned optical ring trap for Bose-Einstein condensates based on conical refraction
A. Turpin, J. Polo, Yu. V. Loiko +6
We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical…
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…
Wave-vector and polarization dependence of conical refraction
A. Turpin, Yu. V. Loiko, T. K. Kalkandjiev +2
We experimentally address the wave-vector and polarization dependence of the internal conical refraction phenomenon by demonstrating that an input light beam of elliptical transver…
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…
Generating a three dimensional dark focus from a single conically refracted light beam
Yu. V. Loiko, A. Turpin, T. K. Kalkandjiev +2
We report here the generation of a three dimensional dark focus from a single focused monochromatic Gaussian beam that undergoes conical refraction when it propagates along one of…
Free Space Optical Polarization De-multiplexing and Multiplexing by means of Conical Refraction
Alex Turpin, Yurii Loiko, Todor K. Kalkandjiev +1
Polarization de-multiplexing and multiplexing by means of conical refraction is proposed to increase the channel capacity for free space optical communication applications. The pro…
