摘要：

Dynamics and bifurcation in a semiconductor laser due to delayed opto-electronic negative feedback are studied. Dynamical stability of the laser is investigated theoret-ically to get formulae of the oscillation frequency and damping of the laser. Routes from bifurcation to chaos are simulated numerically by varying the delayed time, the feedback strength and the current. A physical model of generalized chaotic synchronization in lasers due to delayed opto-electronic conversion is presented. Periodic synchronization, dual-periodic synchronization and cha-otic synchronization are demonstrated numerically and theoretically, respectively. We find that the responding lasers exhibit dynamical characteristics concerning with the driving laser. However, the responding laser shows a different swirling attractor from that of the driving laser. Chaos modulation with a frequency of 0.1 GHz, chaos shift keying with a rate of 0.1 Gbit/s, and chaos masking with a frequency of 0.5 GHz are simulated, respectively. Generalized chaotic synchronization error is calculated. Chaos masking with a frequency of 1 GHz is analysed in detail under the condition of parameter mismatch.
