摘要

提出了一种利用等离子体谐振腔检测折射率变化的传感装置。采用时域有限差分法对该装置的检测性能进行了数值评价。理论上，如果使用波长为633 nm的光作为激发源，该装置可以检测到10的负六次方的折射率变化。我们制作了等离子体方形谐振腔并对其进行了评价。

Development of a sensing device for detecting refractive index changes by using a plasmonic resonator

The authors present a sensing device for detecting refractive index changes by using a plasmonic resonator. The detection performance of the device has been numerically evaluated by the finite-difference time-domain method. The device can detect refractive index changes of 10 to the negative sixth power if a light with the wavelength of 633 nm is used as excitation source, theoretically. We have fabricated the plasmonic square resonator and evaluated it.
