Abstract :
In this letter, we report the strong effect of p-doping on dynamic performances of QDash lasers. Therefore, we demonstrate 10 Gb/s transmission in standard single mode fiber up to 65 km with a dynamic extinction ratio using directly modulated lasers based on this material and commercial Fabry-Pérot etalon filter.
