Abstract

SE PRESENTA UN METODO PARA GENERAR UNA SEÑAL DE SINCRONIZACION A PARTIR DE UNA SEÑAL DE DATOS DIGITALES OPTICOS QUE TENGA UN COMPONENTE DE SINCRONIZACION SIGNIFICATIVO. LA SEÑAL DE DATOS OPTICOS DIGITALES SE INTRODUCE EN EL INTERIOR DE UN DISPOSITIVO OPTOELECTRONICO (1), Y SE DETECTA LA VARIACION NO LINEAL EN EL DISPOSITIVO OPTOELECTRONICO PROVOCADA POR LA SEÑAL DE DATOS OPTICOS DIGITALES EN EL DISPOSITIVO, DANDO COMO RESULTADO LA GENERACION DE UNA SEÑAL ADICIONAL DESDE EL DISPOSITIVO. SE EXTRAE UN COMPONENTE EN UNA FRECUENCIA DE SINCRONIZACION PARA LA SEÑAL DE DATOS OPTICOS DIGITALES A PARTIR DE DICHA SEÑAL ADICIONAL.
