Abstract

In this paper we present the technology and experimental results of the intensity based fiber optic threshold temperature sensor. As an optode of the sensor it was used a patch cord with an organic mixture filled photonic crystal fiber. Under temperature changes the used mixture changes its state from solid to liquid one and this effect decides about intensity of a transmitted light. A fabricated patch cord with VCSEL as a light source can be easy to use, flexible, cheap and low power consuming sensor. The used technology gives a possibility to design optodes with different transition temperatures in order to make sensor arrays.
