We propose a point-to-point or single-ended communications technique based on single-mode optical fibers that uses all-optical pulse multiplexing at the transmitter and coherent optical correlation at the receiver. This technique shows potential for application to secure untappable communications, fiber local-area networks, and optical ranging in the presence of a strong white-light background. The system can employ a low-coherence source, is insensitive to source phase noise and polarization-state rotation in the fiber link, and uses simple electronic threshold detection. Coherent correlation and anticorrelation are demonstrated experimentally, and practical requirements are examined.
我们提出了一种基于单模光纤的点对点或单端通信技术，该技术在发射端采用全光脉冲复用，在接收端采用相干光相关。这种技术在存在强白光背景的情况下，在安全不可窃听通信、光纤局域网和光学测距方面显示出应用潜力。该系统可以采用低相干源，对光纤链路中的源相位噪声和偏振态旋转不敏感，并使用简单的电子阈值检测。通过实验证明了相干相关和反相关，并研究了实际需求。
