A full polymeric optofluidic Fabry–Perot (FP) resonator with a high quality factor (Q) is proposed and tested. The device is based on multilayer optical polymeric films that act as high reflectivity interference mirrors. The all-polymeric laminated structure avoids any deposition or etching process, simplifying the fabrication procedure while retaining a high quality optical surface. The measured quality factor of the FP resonator is ${3.03} \times {{10}^4}$, and the finesse is 91 around 700 nm. The refractometric sensing properties have been measured, and a sensitivity of 314 nm/RIU with a limit of detection of ${2.55} \times {{10}^{- 5}}\;{\rm RIU}$ could be achieved. The device exhibits a very high figure of merit of ${1.36} \times {{10}^4}\;{{\rm RIU}^{- 1}}$ that is comparable with the performance attainable with sensors based on photonic crystal and whispering gallery mode resonators.

全聚合物高Q光电法布里-珀罗谐振器

提出并测试了具有高品质因数（Q）的全聚合物光电流体法布里-珀罗（FP）谐振器。该设备基于充当高反射率干涉镜的多层光学聚合物薄膜。全聚合物层压结构避免了任何沉积或蚀刻过程，简化了制造过程，同时保留了高质量的光学表面。FP谐振器的测得品质因数为$ {3.03}乘以{{10} ^ 4} $，精细度为700 nm左右。已经测量了折射感测特性，并且可以实现314 nm / RIU的灵敏度，检出限为$ {2.55}乘以{{10} ^ {-5}} \; {\ rm RIU} $。该设备显示出很高的品质因数$ {1.36} \ times {{10} ^ 4} \; {{\ rm RIU} ^ {-1}} $ 这与基于光子晶体和耳语画廊模式谐振器的传感器所能达到的性能相当。
