双端口光学器件根据输入光子状态将光耦合到任一端口。一类重要的双端口器件是渐逝耦合界面，其中光子耦合的手性可以导致重要的技术应用。在这里，我们执行这样的接口的基本特性，重建的庞加莱球的光学纳米纤维的表面上的双端口偏振响应。从这个结果中，我们得到了一个手性措施，这是普遍的，遵守一个参数标度律独立的确切参数的纳米纤维和光波长。此外，我们注意到，偏振响应定性不同的单个和多个耦合发射器，与传感和波导耦合自旋的表征可能的影响。
Two port optical devices couple light to either port dependent on the input photon state. An important class of two-port devices is that of evanescently-coupled interfaces where chirality of photon coupling can lead to important technological applications. Here, we perform a fundamental characterization of such an interface, reconstructing the two-port polarization response over the surface of the Poincaré sphere for an optical nanofibre. From this result, we derive a chirality measure which is universal, obeying a one parameter scaling law independent of the exact parameters of the nanofibre and wavelength of light. Additionally, we note that the polarization response differs qualitatively for single and multiple coupled emitters, with possible implications for sensing and the characterization of waveguide coupled spins.
