Over the past decade the acceptance of optical fibre sensors in different fields and industries has increased steadily, largely due to the fact that they represent a viable solution. Presently, there are several types of fibre sensors commercially available; however, there are many opportunities as well as challenges in this research field. For example, the unique optical properties of photonic crystal fibres and nano-scale effects offer outstanding potential for sensing applications that merit to be exploited. On the other hand, improved sensing platforms, new characterization methods and new approaches to devise fibre sensors are needed to overcome the limitations of the existing ones.
This talk will give an overview on our research on new sensing platforms based on photonic crystal fibre interferometers, in-fibre microcavities, and regenerated Bragg gratings. All these platforms are simple, highly versatile, reproducible, and can be used to develop compact and cost-effective discrete sensors to monitor a variety of physical, chemical or biological parameters. Our efforts to use our devices in real-world environments or to commercialize them will be discussed.
