Abstract

PARA LA REGULACION DEL EFECTO OPTICO DE UN LASER CUYA CORRIENTE DE FUNCIONAMIENTO SE COMPONE DE UNA CORRIENTE PREVENTIVA (I.V) Y UNA CORRIENTE DE MODULACION (I.MOD), DONDE AMBAS SE DESCONECTAN CON INDEPENDENCIA DEL EFECTO OPTICO DEL LASER MEDIANTE UN RAYO PARCIAL DEL RAYO LASER Y COMPARACION DE LAS SEÑALES RECIBIDAS CON UNA SEÑAL DE REFERENCIA MEDIANTE UN DISPOSITIVO DE REGULACION, SEGUN EL INVENTO SE PROPONE QUE LA CORRIENTE PREVENTIVA (I.V) Y DADO EL CASO, TAMBIEN LA CORRIENTE DE MODULACION (I.MOD) SE REGULEN DE MODO QUE EL LASER LD TRABAJE EN EL AMBITO DE LAS ROTURAS (CORRIENTE DE UMBRAL (I.S)), PARA QUE UNA DISMINUCION DE LA ANCHURA DE BANDA TRASLADADA O UNA DEMORA DE LA CONEXION, Y CON ELLO UNA LINEA ESPECTRAL, APAREZCA EN EL ESPECTRO EFECTIVO DEL EFECTO OPTICO, DONDE ESTA LINEA ESPECTRAL SE MIDE MEDIANTE UN DISPOSITIVO DE MEDIDA (PD) Y DONDE EL VALOR DE MEDIDA SE CONSTITUYE EN UNA SEÑAL DE DIRECCION QUE ACTUA SOBRE EL DISPOSITIVO DE REGULACION (K1;K2) DE LA CORRIENTE PREVENTIVA (I.V) Y, DADO EL CASO, TAMBIEN DE LA CORRIENTE DE MODULACION (I.MOD), DONDE LA LINEA ESPECTRAL SE MANTIENE EN UN VALOR POR DEBAJO DE UN VALOR MAXIMO ADMISIBLE Y CON ELLO LA CORRIENTE PREVENTIVA SE REGULA POR DEBAJO DE UN VALOR PROXIMO A SU OPTIMO.
