Abstract

UN AMPLIFICADOR OPTICO PARA AMPLIFICAR SEÑALES DE DIFERENTES LONGITUDES DE ONDA POR MEDIO DE UNA VENTANA ESPECTRAL, MODIFICA LA AMPLIFICACION DE CADA SEÑAL EN TAL FORMA QUE LOS NIVELES DE SALIDA DE LAS SEÑALES SON MAS IGUALES QUE LOS NIVELES DE ENTRADA DE LAS MISMAS, CUANDO LOS NIVELES DE ENTRADA DIFIEREN EN MAS DE UNA CANTIDAD PREVIAMENTE DETERMINADA. EN UNA VERSION, ESTO SE OBTIENE PROPORCIONANDO UN REFLECTOR 120 DICROICO EN UN EXTREMO DE UNA FIBRA DE AMPLIFICACION, CON LO QUE LOS FORMATOS DE LAS ONDAS ESTACIONARIAS SE ESTABLECEN EN LA FIBRA DE AMPLIFICACION MEDIANTE LA INTERFERENCIA DE LAS LUCES DE SEÑALES DIRECTAS Y REFLEJADAS (CALCINACION DE AGUJEROS ESPECIALES), EN DIFERENTES LONGITUDES DE ONDA, DISMINUYENDO PREFERENCIALMENTE LA SEÑAL DE CADA LONGITUD DE ONDA SU PROPIA GANANCIA O INCREMENTO CON EL AUMENTO DEL NIVEL DE LA SEÑAL.
