Abstract

Un diodo láser (1) es accionado por un primer amplificador integrado (5) que recibe un voltaje de referencia de corriente directa V ref, datos de entrada Vin, y realimentacion negativa desde un fotodiodo de faceta posterior (2) y mediante un segundo amplificador de banda ancha que recibe los datos y la realimentacion negativa.
