利用线性光学采样测量系统测量了两种耦合双芯光纤的复冲激响应。测量在20 nm的带宽（~ 2.5 THz）上进行，并分析了空间模式色散（SMD）。制备了几种长度的均质和非均质芯光纤，以研究SMD的长度依赖性。通过数值分析测量的宽带冲激响应来检查用于划分频带的SMD。因此，在每个子带的功率脉冲响应，并在SMD的变化进行了检查。此外，SMD的统计分布被揭示为不同的每种类型的2芯光纤。在空分复用传输系统中，在特定频带处观察到的SMD由接收机处理。最后，我们给出了一个双芯光纤的模相关损耗（MDL）的测量，并讨论了时间轴的不准确性对MDL测量的影响。这些分析预计将有利于设计这样的系统。
The complex impulse responses of two types of coupled 2-core fibers, with homogeneous and heterogeneous cores, were measured by using a measurement system based on linear optical sampling. The measurements were performed over a bandwidth of 20 nm (∼2.5 THz), and the spatial-mode dispersion (SMD) was analyzed. Several lengths of both homogeneous and heterogeneous core fibers were prepared to investigate the length dependence of SMD. The SMDs for divided frequency bands were examined by numerically analyzing the measured broadband impulse response. Consequently, the power impulse response at each subband was obtained, and the variation in the SMDs was examined. In addition, the statistical distribution of the SMD was revealed to be different for each type of the 2-core fiber. The SMD observed at a specific band is handled by the receiver in space-division multiplexing transmission systems. Finally, we present a measurement of mode dependent loss (MDL) of a 2-core fiber, and discuss the impact of time axis inaccuracy to the MDL measurement. These analyses performed are expected to be beneficial for designing such systems.
