Description
El presente texto expone un modelo preliminar para un codificador optoelectrónico que busca explotar la propiedad del momento angular orbital de la luz para la transferencia de datos. La implementación de esta tecnología proporciona una serie de ventajas en la criptografía cuántica, en el aumento de ancho de banda e incluso en el almacenamiento de arreglos. Se presenta una arquitectura a nivel de capa física en forma de diagrama de bloques, luego se desarrolla la teoría matemática en la que se basa el codificador, donde se utiliza la aproximación paraxial de la onda que se propaga en cavidades resonantes tipo Hermite-Gauss y Laguerre-Gauss. Se analizan tres posibles técnicas para la generación de la magnitud física y la posterior inserción del dato, se selecciona la más versátil y se muestran las principales particularidades tanto del haz incidente como del haz que emerge del codificador.
This paper presents a preliminary model for optoelectronic encoder that use the property of orbital angular momentum of light to data transfer. The implementation of this technology provides some advantages in quantum cryptography, increasing bandwidth even storing arrangements.This architecture is showed in blocks diagram and a brief mathematical theory to explain the encoder is presented, it uses the wave’s paraxial approximation when propagates out of resonant cavities like Hermite-Gauss or Laguerre-Gauss. Three possible techniques allow the generation of the physical quantity of interest, topological charge of the beam, and the subsequent insertion of the data to transmit, selecting the most versatile and showing the main characteristics of both, the incident beam and the beam emerging from the encoder.
