Radial coherent and intelligent states of paraxial wave equation
Ebrahim Karimi, Enrico Santamato
Ladder operators for the radial index of the paraxial optical modes in the cylindrical coordinates are calculated. The operators obey the su(1,1) algebra commutation relations. Bas…
Generation and dynamics of optical beams with polarization singularities
Filippo Cardano, Ebrahim Karimi, Lorenzo Marrucci +2
We present a convenient method to generate vector beams of light having polarization singularities on their axis, via partial spin-to-orbital angular momentum conversion in a suita…
Time-division multiplexing of the orbital angular momentum of light
Ebrahim Karimi, Lorenzo Marrucci, Corrado de Lisio +1
We present an optical setup for generating a sequence of light pulses in which the orbital angular momentum (OAM) degree of freedom is correlated with the temporal one. The setup i…
Spin-to-Orbital Angular Momentum Conversion and Spin-Polarization Filtering in Electron Beams
Ebrahim Karimi, Lorenzo Marrucci, Vincenzo Grillo +1
We propose the design of a space-variant Wien filter for electron beams that induces a spin half-turn and converts the corresponding spin angular momentum variation into orbital an…
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…
Laser-induced radial birefringence and spin-to-orbital optical angular momentum conversion in silver-doped glasses
Jafar Mostafavi Amjad, Hamid Reza Khalesifard, Sergei Slussarenko +3
Samples of Ag/Na ion-exchanged glass that have been subject to intense laser irradiation may develop novel optical properties, as a consequence of the formation of patter…
