Superposition of two optical vortices with opposite integer or non-integer orbital angular momentum
This work develops a brief proposal to achieve the superposition of two opposite vortex beams, both with integer or non-integer mean value of the orbital angular momentum. The first part is about the generation of this kind of spatial light distributions through a modified Brown and Lohmann’s hologr...

En primera instancia se aborda la generación de éste tipo de distribuciones espaciales de luz a través del holograma modificado de Brown y Lohmann. Posteriormente se inserta un sencillo artificio matemático sobre la función de transmitancia de la rejilla pixelada basado en las propiedades del espacio de Fourier, para lograr desplazar los órdenes de difracción de sentidos levógiro y dextrógiro a un mismo punto espacial y efectuar la suma de los modos. Se valida la estrategia de manera teórico experimental para el caso de los dos frentes de onda helicoidales opuestos en rotación.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/43948Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónDíaz Meza, Carlos Fernando and Torres Moreno, Yezid and Acevedo Cáceres, Cristian Hernando (2016) Superposition of two optical vortices with opposite integer or non-integer orbital angular momentum.
