摘要：
The bandwidth of chaotic signal in vertical-cavity surface-emitting lasers with optical injection has been studied experimentally. The results show that the bandwidth of chaotic signal, which is dependent on the frequency de-tuning and injection strength, can be enhanced by a factor of more than two with appropriate optical injection. Under certain conditions, optical injection can also result in a reduction of the chaotic signal bandwidth. (C) 2012 Optical Society of America
