We report on the realization of a hybrid chaos-based communication scheme using three chaotic semiconductor ring lasers (SRLs). In this scheme, two slave SRLs (S-SRLs) are identically driven by a master SRL (M-SRL) subject to delayed optical feedback. Under proper conditions, the S-SRLs are completely synchronized with each other due to the symmetric operation, and they are also synchronized with the M-SRL through the injection-locking effect. The results also show that a message encrypted through chaos shift keying at the M-SRL end can be successfully decrypted by the two S-SRLs, while the two uncoupled S-SRLs allow for dual-channel chaos communication when both counterpropagating modes of one S-SRL are encoded with a message.
我们报告了一种使用三个混沌半导体环形激光器（SRL）实现的基于混合混沌的通信方案。在该方案中，两个从SRL（S-SRL）由一个受延迟光反馈影响的主SRL（M-SRL）以相同方式驱动。在适当条件下，由于对称操作，S-SRL彼此完全同步，并且它们还通过注入锁定效应与M-SRL同步。结果还表明，在M-SRL端通过混沌键控加密的消息可以被两个S-SRL成功解密，而当一个S-SRL的两个反向传播模式都用消息编码时，两个未耦合的S-SRL可实现双通道混沌通信。
