“…Depending on the number of times the fiber is dipped and other parameters such as immersion speed, dye, or deposition techniques, the new claddings will have different thickness' and surfaces. A simpler variation of this technique consists of just soaking the fiber for a certain time in the mixture where the analyte is added [19, 44]. The final deposition has to be mechanically resistant, and it is also desirable that its properties remain temporally invariable.…”

Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and interesting properties which overcame some of the inconveniences found on traditional gas sensors appeared over two decades ago. Thanks to its minimum invasive nature and the advantages that optical fiber offers such as light weight, passive nature, low attenuation and the possibility of multiplexing, among others, these sensors are a real alternative to electronic ones in electrically noisy environments where electronic sensors cannot operate correctly. In the present work, a classification of these devices has been made according to the sensing mechanism and taking also into account the sensing materials or the different methods of fabrication. In addition, some solutions already implemented for the detection of VOCs using optical fiber sensors will be described with detail.
