Abstract

In this paper, a linearly chirped fiber Bragg grating (CFBG) inscribed in a microstructured polymer optical fiber (mPOF) has been demonstrated for detecting temperature profiles during thermal treatments. A CFBG of 10-mm length and 0.98-nm bandwidth has been inscribed in an mPOF fiber by means of a KrF laser and uniform phase mask. The CFBG has a high temperature sensitivity of-191.4 pm C. The CFBG has been used as a semidistributed temperature sensor, capable of detecting the temperature profile along the grating length, for scenarios that account minimally invasive biomedical treatments. Two experiments have been designed to validate the CFBG temperature reconstruction, using a linear gradient, and a research-grade radiofrequency ablation setup to apply Gaussian-shaped temperature spatial profiles. The result is that the higher sensitivity of the CFBG supports the detection of spatially nonuniform temperature fields by means of spectral reconstruction.
