✦ Synopsis

Detailed experimental mappings of the dynamics of a Fabry-Pe ´rot type semiconductor laser subjected to external optical injection along with parameters describing the injected laser have been published by Eriksson and Lindberg [J. Opt. B: Quantum Semiclass. Opt. 4 (2002) 149] and by Eriksson [Opt. Commun. 210 (2002) 343]. This paper reports on a numerical investigation of the injection experiments. By computing the largest Lyapunov exponent, the chaotic islands, periodic windows and locking ranges are compared in detail with the experimental results for three different operating points of the laser. The numerical results are in good agreement with the experiment once the linewidth enhancement factor is increased from the earlier reported value of 3.9 ± 0.5 to about 6.7. The new value is confirmed by a re-measurement of the linewidth enhancement factor using a current modulation technique.

The frequency spectrum and the power output of a weakly optically-injected semiconductor laser in a period-one state are investigated. It is found that the oscillations in the power output consist of three components each caused by different physical effects, namely the relaxation oscillation freque

## Abstract We have experimentally demonstrated a new optical microwave signal generation scheme using semiconductor lasers in a master–slave configuration, in which both lasers are directly modulated. The sidebands of the slave laser are locked to those of the master laser by the simple control of
