Nonlinear dynamical characteristics of a slave semiconductor laser (S-SL) subject to optical injection from a master SL (M-SL) and optical feedback from a fiber Bragg grating (FBG) are investigated experimentally. First, we investigate the nonlinear dynamics of the S-SL subject to only optical injection. Through varying the injection coefficient and fixing the frequency detuning between the M-SL and S-SL, some dynamical states with typical characteristics are recorded and identified. Next, the variations of these dynamical states are further investigated with the introduction of a FBG feedback, and the according results show that these dynamical states may be changed after a FBG feedback is introduced into the S-SL. Finally, after collecting the mappings of the dynamical states of S-SL in the parameter space of injection coefficient and frequency detuning under different FBG feedback coefficients, the influences of FBG feedback on the nonlinear dynamics of the S-SL are analyzed. •Nonlinear dynamics of a semiconductor laser (SL) subject to optical injection and FBG feedback is studied experimentally.•The Introduction of FBG feedback change the distribution region of different dynamical states of an optically injected SL in the parameter space of the injection coefficient and frequency detuning.•Through adjusting related parameters of injection light and FBG feedback, the output dynamical state of SLs can be controlled easily to meet different applications.
