Abstract

We demonstrated a biocompatible temperature sensor using single mode tapered fiber and DNA-CTMA(DNA-Cetyl tri-methyl ammonium) solid film. DNA-CTMA was coated on the tapered region, which is an interferometer. The spectral change with temperature was measured due to the refractive index changes of DNA-CTMA according to temperature. The range of the temperature change was from 35 to 65°C, and the sensitivity was-0.91 nm/'C. Furthermore, confirmed that the stain sensitivity of this sensor was-19 pm/us.
