Guiding light via geometric phases
Sergei Slussarenko, Alessandro Alberucci, Chandroth P. Jisha +4
Known methods for transverse confinement and guidance of light can be grouped into a few basic mechanisms, the most common being metallic reflection, total internal reflection and…
Nodal Areas and Structured Darkness
Garreth J. Ruane, Sergei Slussarenko, Lorenzo Marrucci +1
Generalized beams of light that are made to turn inside out, creating black nodal areas of total destructive interference are described. As an example we experimentally created an…
Direct measurement of the orbital angular momentum mean and variance in an arbitrary paraxial optical field
Bruno Piccirillo, Sergei Slussarenko, Lorenzo Marrucci +1
We introduce and experimentally demonstrate a method for measuring at the same time the mean and the variance of the photonic orbital angular momentum (OAM) distribution in any par…
Reconstructing the Poynting vector skew angle and wave-front of optical vortex beams via two-channel moiré deflectometery
Mohammad Yeganeh, Saifollah Rasouli, Mohsen Dashti +3
A novel approach based on the two-channel moiré deflectometry has been used to measure both wave-front and transverse component of the Poynting vector of an optical vortex beam. Ge…
Liquid crystal spatial-mode converters for the orbital angular momentum of light
Sergei Slussarenko, Bruno Piccirillo, Vladimir Chigrinov +2
We present a tunable liquid crystal device that converts pure orbital angular momentum eigenmodes of a light beam into equal-weight superpositions of opposite-handed eigenmodes and…
Polarization pattern of vector vortex beams generated by -plates with different topological charges
Filippo Cardano, Ebrahim Karimi, Sergei Slussarenko +3
We describe the polarization topology of the vector beams emerging from a patterned birefringent liquid crystal plate with a topological charge at its center (-plate). The p…
