摘要

实验证明了Mach-Zehnder干涉仪耦合微环具有高灵敏度(~111 nm /RIU)、高消光比(>26dB)和非常大的准自由光谱范围(>100 nm)，这有助于获得大的测量范围。当环境材料的反射指数发生较大变化时，mzi耦合微环传感器仍然具有良好的性能(1)

Silicon-nanowire-based optical sensor with high sensitivity and large measurement range by using Mach-Zehnder interferometer-coupled microring

A Mach-Zehnder interferometer-coupled microring is experimentally demonstrated for optical sensing with a high sensitivity (~111 nm /RIU), a high extinction ratio (>26dB), and a very large quasi free-spectral-range (>100 nm), which helps to obtain a large measurement range. The MZI-coupled microring sensor still has good performance when the reflective index of the ambient materials largely changes (1
