The linewidth enhancement factor (Alpha factor) is a key parameter in optical system design in terms of both continuous wave operation and high frequency modulation conditions. Since the linewidth is reduced in external cavity configuration by weak optical feedback, the role of Alpha factor is simulated in such a condition. Both the values of Alpha and feedback parameters are optimised in such a system.
