Abstract :
Feedback effects in a laser diode due to Rayleigh back-scattering in a 50 m fibre with or without end reflections are reported. Linewidth reduction by more than 200 and wavelength instability on a millisecond scale are observed. An analytical model based on the statistical nature of the back-scattering shows good agreement with the experimental results.
