Abstract

This paper shows the experimental and theoretical results obtained for encoding data using light beams with different values of orbital angular momentum. Light beams with orbital angular momentum were generated using holographic masks with different values of topological charge, an displayed using a transmission spatial light modulator. Furthermore, we showed the results obtained for the characterization of the spatial light modulator in the amplitude-coupled regime by using the retarder-rotor model.


El presente trabajo muestra los resultados experimentales y teóricos obtenidos para la codificación de datos utilizando haces luminosos con diferentes valores de momento angular orbital. Los haces luminosos con momento angular orbital fueron generados utilizando mascaras holográficas con diferentes valores de carga topológica, y desplegadas dinámicamente empleando un modulador espacial de luz por transmisión. Además se muestran los resultados obtenidos para la caracterización del modulador espacial de luz en el régimen acoplado en intensidad usando el modelo retardador-rotor.
