摘要：
A novel system of chaotic oscillation frequency enhancement and control of chaos in two spatial coupled semiconductor lasers due to optical feedback is presented. Characteristic of chaotic frequency enhancement and control of chaos in the lasers are studied and a static frequency detuning formula is given. For the case of single-laser feedback, chaotic enhancements are effectively achieved when the feedback is at high levels, in which, the strong feedback can result obviously in frequency enhancement in the dual-lasers while the frequency can be enlarged to 3.57 times of the intrinsic frequency of one laser and 2.86 times for the other. Chaos-control region is found in low feedback levels. In this region, dual-lasers can be conduced to single-cycle, dual-cycle and triple-cycle. The frequency can be enlarged to 3 times of the intrinsic frequency of one laser and 2.58 times for the other when the dual-lasers are with the feedback. Chaos-control region is also found in low feedback levels, and dual-lasers can be controlled to single-cycle, dual-cycle and triple-cycle. The developing path from single-cycle locking to quasi-cycle and then to chaotic frequency enhancement is put forward in detail when the single-feedback or the dual-feedback is present.
