Abstract

SE CONSIGUE UN MODO UNICO MEJORADO EN LASER DE REALIMENTACION DISTRIBUIDA (DFB) REDUCIENDO AL MINIMO LA REALIMENTACION PROPORCIONADA EN, O CERCA DE, LOS EXTREMOS DEL ENREJADO DFB. LA REALIMENTACION PUEDE REDUCIRSE AL MINIMO EN UNO O EN AMBOS EXTREMOS DEL ENREJADO. LA REALIMENTACION SE CONTROLA REDUCIENDO EL ACOPLAMIENTO DEL ENREJADO. EL ACOPLAMIENTO SE REDUCE, DISMINUYENDO LA PROFUNDIDAD DE LOS DIENTES DEL ENREJADO Y/O AUMENTANDO EL ESPACIAMIENTO ENTRE DIENTES ADYACENTES
