Linewidth reduction of semiconductor lasers and study of linewidth property
In this paper, principles of linewidth reduction of external cavity semiconductor lasers are analyzed. Linewidth measurement is performed by the Delayed Self Heterodyne Method. It is obtained experimentally that laser linewidth is reversely proportional to laser output power and external cavity feedback level.
