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…

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…
