Lab-on-Fiber devices as an all around platform for sensing

On this line, in this work we first provide a brief review of the main achievements in the Lab-on-Fiber roadmap, including the first demonstrations of fabrication processes which have led to novel highly functionalized optical nanoprobes of particular impact on the sensing field. Successively with reference to an optical device recently proposed by our group and full expression of the Lab-on-Fiber concept, we carry out an exhaustive numerical analysis aimed at demonstrating the extreme versatility of this device; we show how it is possible to exploit all the degrees of freedom it offers, in order to achieve the complete control on the number and the field distribution of the resonant modes (and the consequent spectral features) that determine the device performances for a specific application. Overall, our study highlights the enormous potentialities and achievements of the Lab-on-Fiber technology that are leading it to be one of the hottest topics in photonics community.
