Abstract :
We report the dependence of receiver sensitivity on laser linewidth for a series of ASK heterodyne experiments performed with 1.5 ¿m distributed feedback lasers and external cavity lasers, and the result of an error-free heterodyne transmission experiment at 150 Mbit/s over 102 km of fibre using the external cavity lasers.
