| 摘 要： | 提出了基于延迟非相干光反馈与非相干光注入的级联混沌同步方案,与相干方案相比,该方案不需要频率完全匹配.数值研究结果表明,在其他参量匹配的情况下,发送机与接收机能实现完全同步.通过混沌键控方法,实现了信息的编码与解码.由于该级联方案具有非相干,宽带宽和多信息点传输的特点,所以在物理实现上很有吸引力,在全光中继通信方面也存在着很大的潜力.

| Abstract: | A synchronization scheme of three cascade chaotic lasers subject to incoherent optical feedback and incoherent optical injection is proposed. Compared with coherent ones, the fine tuning of optical frequencies is not required in this scheme. Numerical simulations indicate that under parameters matched, complete synchronization can be obtained between the transmitter and receiver lasers. Message coding and decoding is shown by chaos shift keying (CSK). The cascade scheme is remarkable for incoherence, wideband and multipoint message transmission,therefore attractive to physical realization and potential for all-optical relay communication. |
