Control of chaos in a gain-modulated feedback semiconductor laser is studied via performing the dual-polarizing light. The laser dynamic physical models of the delay feedback orthogonal polarizing light, the π/2-rotated polarization, the synchronous polarizing directional light are presented, respectively. The chaotic laser can be controlled by adjusting the mirror in external optical path to control the delay time of the polarizing light, or conversing one polarizing light at another polarizing direction, or compensating phase of polarizing light via the polarimeter. Numerical results illustrate that the chaotic laser can be controlled to periodic states.
