Abstract

UN CONTROLADOR DE MODULACION LASER (10) PREVE UN CONTROL DE MODULACION LASER POR POLARIZACION CC (54) HACIA UN LASER (86) CON UN PRIMER TONTO DE CONTROL (34), MODULACION DE AMPLITUD (18) DE UNA SEÑAL DE TRABAJO DE ENTRADA DE NO RETORNO A CERO (NRZ) (12) PARA CONVERTIRSE EN SALIDA LUMINOSA CON UN SEGUNDO TONO DE CONTROL (70), DETECTANDO EL PRIMER TONO DE CONTROL A PARTIR DE UNA PARTE DE LA SALIDA LUMINOSA DEL LASER (88, 26) COMO UNA TERCERA SEÑAL VAGC) QUE SE INVIERTE PROPORCIONALMENTE A LA GANANCIA LASER, DETECTANDO EL SEGUNDO TONO DE CONTROL A PARTIR DE UNA PARTE DE LA SALIDA LUMINOSA DEL LASER COMO UNA CUARTA SEÑAL (VAM) QUE SE DA SOLAMENTE SI EL LASER ESTA SIENDO MODULADO EN O POR DEBAJO DE LA REGION DE UMBRAL DE LASER, Y COMBINANDO SUBRACTIVAMENTE LA TERCERA Y LA CUARTA SEÑAL PARA GENERAR UNA QUINTA SEÑAL VAGC-VAM PARA SU USO COMO CONTROL DE LA AMPLITUD DE LA SEÑAL DE TRABAJO NRZ (18). EN LUGAR DE USAR VAGC COMO SEÑAL DE REALIMENTACION QUE DA COMO RESULTADO DOS PUNTOS OPERATIVOS ESTABLES (FIG.3) EL USO DE VAGC-VAM DA COMO RESULTADO SOLAMENTE UN PUNTO OPERATIVO ESTABLE (FIG. 3D).
