Passive optical tapping can be implemented by stacking multiple layers of polydimethylsiloxane (PDMS), which is used as planar waveguides for the transmission and capturing of light. Once the main waveguide is installed in the communications system, each additional stacked waveguide represents an optical sniffer where it is possible to intercept the data from an input optical fibre, allowing the information to also flow to the output fibre unnoticeably from the point of view of the transmitter. The waveguides can be stacked or removed, making it a dynamic device that overcomes the limitations of previous designs, and the optical sniffer shows fixed implementation. In addition, it is demonstrated that PDMS is a versatile material that permits the control of the coupling of light among the waveguides, depending on its properties, and the thickness of each waveguide is also critical for the performance of the device. Furthermore, the experimental results are supported with a theoretical analysis that permits better understanding of the performance of the device, whose use can be extended to other applications, such as a passive optical hub or a signal combiner/splitter.

侵入式无源光学攻丝装置

可以通过堆叠多层聚二甲基硅氧烷（PDMS）来实现无源光抽头，该层用作平面波导，用于传输和捕获光。一旦将主波导安装在通信系统中，每个附加的堆叠波导就代表一个光学嗅探器，在这里可以截取来自输入光纤的数据，从以下观点来看，信息也可以显着地流向输出光纤。发射器。波导可以堆叠或拆除，使其成为一种动态设备，可以克服先前设计的局限性，并且光学嗅探器显示出固定的实现方式。此外，已证明PDMS是一种通用材料，可根据其特性控制波导之间的光耦合，每个波导的厚度对于设备的性能也至关重要。此外，实验结果得到理论分析的支持，该理论分析可以更好地了解设备的性能，该设备的应用可以扩展到其他应用，例如无源光集线器或信号组合器/分离器。
