Abstract :
We proposed a method of measuring the intrinsic linewidth of semiconductor lasers, by using self-heterodyne method with multiple measurements of different delay fiber lengths. By eliminating the 1/ f noise effects, the linewidth becomes much smaller than the conventional measurement method.
