Abstract

SE DESCRIBE UN ESPEJO DE CONJUGACION DE FASE AUTO©BOMBEADO Y METODO EN EL QUE SE APLICA UN RAYO OPTICO (20) A UN CRISTAL (18) FORMADO DE UN MATERIAL FOTO©REFRACTIVO, EL RAYO ES DESVIADO HACIA ATRAS AL CRISTAL COMO UN RAYO DE RETORNO (30) PARA SU ACOPLAMIENTO CRUZADO COMO UN RAYO DE RETORNO (30) PARA SU ACOPLAMIENTO CRUZADO CON EL RAYO DE SONDA (20) DE ENTRADA Y SE APLICA UN CAMPO ELECTRICO ALTERNATIVO A TRAVES DEL CRISTAL PARA ESTABLECER UN DESPLAZAMIENTO DE REJILLA DE INDICE FOTO©REFRACTIVO DE APROXIMADAMENTE 90J Y AUMENTAR LA GANANCIA DEL CRISTAL HASTA UN NIVEL AL QUE TIENE LUGAR LA CONJUGACION DE FASE. MEDIANTE UNA SELECCION ADECUADA DE LA INTENSIDAD Y FRECUENCIA DEL CAMPO, Y UN ANGULO ENTRE LOS RAYOS DE SONDA Y DE RETORNO DENTRO DEL CRISTAL MENOR DE APROXIMADAMENTE 5J (3J PARA EL GAAS), SE PUEDEN USAR MATERIALES SEMICONDUCTORES CON COEFICIENTES ELECTRO©OPTICOS MENORES DE APROXIMADAMENTE 10 PICOMETROS/VOLTIO COMO MEDIO DE CONJUGACION.
