“…The large amount of available materials enables the development of optical fiber sensors for a wide range of applications [63,102,103,104,105]. Besides the research on the appropriate materials, LMR supporting structures have evolved and they have been studied on a wide range of optical fibers.…”

A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical fibers present several advantages over electronic sensors and great research efforts have been made in recent years in this field. The present paper reports the current trends of optical fiber humidity sensors. The evolution of optical structures developed towards humidity sensing, as well as the novel materials used for this purpose, will be analyzed. Well-known optical structures, such as long-period fiber gratings or fiber Bragg gratings, are still being studied towards an enhancement of their sensitivity. Sensors based on lossy mode resonances constitute a platform that combines high sensitivity with low complexity, both in terms of their fabrication process and the equipment required. Novel structures, such as resonators, are being studied in order to improve the resolution of humidity sensors. Moreover, recent research on polymer optical fibers suggests that the sensitivity of this kind of sensor has not yet reached its limit. Therefore, there is still room for improvement in terms of sensitivity and resolution.

“…angles approaching 90º [5]. This explains why most of the experimental work on LMRs uses optical fibre instead of the Kretschmann-Raether configuration [7,[10][11][12][13][14][15]. With this last configuration, it is very difficult to impinge light at nearly 90º.…”

Lossy mode resonances (LMRs) are typically obtained with optical fibre. The Kretschmann configuration is an alternative but LMRs are generated with angles approaching grazing incidence. In this work, a new setup is explored, based on the lateral incidence of light on conventional planar waveguides such as glass slides or coverslips. Indium tin oxide was deposited onto both types of waveguides generating LMRs. The results of the simulations carried out agree well with the experimental results. As an example of the potential of this new and simple optical configuration, a humidity sensor with a sensitivity of 0.212 nm/%RH in the range from 65 to 90% of RH was developed, which expedites the development of other types of sensors already explored with LMR based optical fibre sensors.

“…The fact that a different deposition technique and different reagents are used in this research implies that the optical properties of the fabricated film may be quite different, which could have caused this unexpected result. Another experimental use of TiO2 for the fabrication of optical LMR sensors was reported, seeking to design an ammonia sensor [52]. This work reports a TiO2 based coating deposited onto a tapered SMF by liquid phase deposition (LPD) process.…”

Lossy mode resonance based sensors have been extensively studied in recent years. The versatility of the lossy mode resonance phenomenon has led to the development of sensors based on different configurations that make use of a wide range of materials. The coating material is one of the key elements in the performance of a refractometer. This review paper intends to provide a global view of the wide range of coating materials available for the development of lossy mode resonance based refractometers.
