Abstract: In this paper, we present a miniature fiber-optic CO2 sensor by in-situ printing of a special polymer Fabry-PĂ©rot (FP) microcavity on the end face of standard single-mode optical fiber. A photo-crosslinkable poly(ionic liquid) (PIL) with high CO2 adsorption capability was employed to fabricate the polymer optical microcavity via an optical 3D p-printing technology. Experimental results show that the optical CO2 microsensor has very high sensitivity and fast response time and thus is very promising for environment and exhaust gas monitoring applications.
