Abstract

SE EXPONE UN DISPOSITIVO OPTICAMENTE ACTIVO QUE COMPRENDE UNA FIBRA OPTICA (10), UNA FUENTE LUMINOSA (12) Y UN DISPOSITIVO OPTICO (13). LA FIBRA OPTICA (10) COMPRENDE UN NUCLEO HECHO DE UN CRISTAL DE FUNCIONAMIENTO OPTICO DOTADO CON PR ELEVADO * COMO ION ACTIVO Y QUE TRANSMITE LA LUZ EN SU PRIMERA LONGITUD DE ONDA. LA FUENTE LUMINOSA (12) GENERA UNA LUZ DE EXCITACION, EN UNA SEGUNDA LONGITUD DE ONDA MENOR QUE LA PRIMERA. EL DISPOSITIVO OPTICO (13) DIRIGE LA LUZ DE EXCITACION DESDE LA FUENTE LUMINOSA (12) HACIA LA FIBRA OPTICA (10). DESPUES, PR ELEVADO * EN EL NUCLEO DE LA FIBRA OPTICA (10) SE ESTIMULA PARA QUE EMITA LUZ EN LA SEGUNDA LONGITUD DE ONDA. COMO RESULTADO, PODRA EFECTUARSE UNA FUNCION OPTICA, TAL COMO UNA AMPLIFICACION OPTICA, EN LA SEGUNDA LONGITUD DE ONDA.
