“…Furthermore, the gas samples could diffuse in and out of the air core without destroying the waveguide structure, and the open channel will not arise excess loss. These advantages will make it very useful for advanced gas sensing with high sensitivity and quick response [85]. J.K. Ranka et al analyzed in [86] the waveguide properties of an SC-PCF consisting of a silica core surrounded by a single ring of large air holes (see Figure 9).…”

Since the first publications related to microstructured optical fibers (MOFs), the development of optical fiber sensors (OFS) based on them has attracted the interest of many research groups because of the market niches that can take advantage of their specific features. Due to their unique structure based on a certain distribution of air holes, MOFs are especially useful for sensing applications: on one hand, the increased coupling of guided modes into the cladding or the holes enhances significantly the interaction with sensing films deposited there; on the other hand, MOF air holes enhance the direct interaction between the light and the analytes that get into in these cavities. Consequently, the sensitivity when detecting liquids, gasses or volatile organic compounds (VOCs) is significantly improved. This paper is focused on the reported sensors that have been developed with MOFs which are applied to detection of gases and VOCs, highlighting the advantages that this type of fiber offers.
