Abstract :
We present measurements of the linewidth reduction for a semiconductor laser exposed to the Rayleigh backscatter from a single-mode fibre. The linewidth is measured as a function of fibre length and laser to fibre coupling efficiency and shows good agreement with the estimate from a simple statistical model.
