Abstract

We report fabrication of a high pressure nonadiabatic tapered optical fiber (NATOF) for downhole applications by using a mechanical transducer. The mechanical transducer has been used for increasing the pressure sensitivity and possibility of installation the sensor in downhole. The NATOF is fabricated by heat pulling method, utilizing a CO₂ laser. The limit of detection of the NATOF was 15 psi.
