Abstract

We designed a temperature sensor by using a D-shape fiber coated with indium tin oxide as a sensing probe. D-shape fiber was fabricated out of conventional single mode fiber by a homemade setup using wheel polishing technique. Insertion loss of D-shape fiber was about 3.5 dB. ITO was deposited over the D-shape fiber by electron-beam deposition technique to have precise deposition of 60nm thin film over the D-shape region of fiber to be utilized as a sensor. It is observed that the transmitted power increased with the increase in temperature with a sensitivity of 0. 0013 dBm/°C. The proposed sensor also provides a good linearity and stability.
