基于两个1550 nm垂直腔面发射激光器(VCSEL)之间的偏振分辨混沌同步，提出了一种新型的长距离双通道双向混沌通信系统。在该系统中，一个驱动垂直腔面发射激光器(D-VCSEL)在双外腔反馈(DECF)下产生一个时延抑制的混沌信号，通过变偏振光注入(VPOI)同时注入到两个垂直腔面发射激光器(VCSEL)中，以实现它们的同步，从而提高两个VCSEL的混沌输出带宽。模拟结果表明，在适当的注入参数下，双VCSEL之间可以实现高质量的偏振分辨混沌同步，同时双VCSEL输出的混沌信号的带宽较驱动混沌信号的带宽有所提高。基于高质量的偏振分辨混沌同步，采用偏振分复用和混沌掩蔽技术，在单模光纤链路中传输15 GHz后，可以有效地解密隐藏在4个混沌载波中的4个10 Gb/S信息。采用色散移位光纤(DSF)作为光纤链路后，双通道双向混沌通信距离可延长到140公里。
Based on the polarization-resolved chaos synchronization between twin 1550 nm vertical-cavity surface-emitting lasers (VCSELs), a novel long-haul dual-channel bidirectional chaos communication system is proposed. In this system, a time delay signature (TDS)-suppressed chaotic signal, generated by a driving VCSEL (D-VCSEL) under double external cavity feedbacks (DECFs), simultaneously injects into twin VCSELs by variable-polarization optical injection (VPOI) to synchronize them and enhance the chaos output bandwidth of the two VCSELs. The simulated results show that, under proper injection parameters, high-quality polarization-resolved chaos synchronization between the twin VCSELs can be achieved; meanwhile the bandwidths of chaotic signals output from the twin VCSELs have been enhanced in comparison with that of the driven chaotic signal. Based on the high-quality polarization-resolved chaos synchronization, after adopting polarization-division-multiplexing (PDM) and chaos masking (CM) techniques, four 10 Gb/s messages hidden respectively in four chaotic carriers can be decrypted effectively after propagating 15 km in single-mode fiber (SMF) links. After adopting dispersion-shifted fibers (DSFs) as fiber links, the dual-channel bidirectional chaos communication distance can be extended to 140 km.
