Resumen-La birrefringencia por efecto electro-óptico depende del tipo de cristal, del corte del cristal, del campo eléctrico aplicado y de la dirección de incidencia de la luz sobre las caras principales del cristal. Se presenta un estudio de maximización de la birrefringencia en cristales fotorrefractivos de simetría cristalográfica cúbica, en términos de estos tres parámetros. Expresiones analíticas generales para la birrefringencia fueron obtenidas, a partir de las cuales se puede establecer la birrefringencia de cualquier tipo de corte. Un nuevo corte cristalográfico fue encontrado, cuyo valor de birrefringencia es mayor que los cortes comerciales PROM, PRIZ y HUIGNARD.Palabras clave-Cristales fotorrefractivos; Birrefringencia; Efecto electro-óptico.Abstract-The electro-optical birefringence effect depends on the crystal type, cut crystal, applied electric field and the incidence direction of light on the principal crystal faces. It is presented a study of maximizing the birefringence in photorefractive crystals of cubic crystallographic symmetry, in terms of these three parameters. General analytical expressions for the birefringence were obtained, from which birefringence can be established for any type of cut. A new crystallographic cut was encountered; the birefringence value is greater than PROM, PRIZ and HUIGNARD commercial cuts.
