报告摘要：Given the continuously increasing interest in fiber-optic sensing and biosensing, the aim of this lecture is to provide a metrological assessment of resonance-based fiber-optic devices towards an objective evaluation of the performance, as well to detail some examples of real applications studied during my carrier. In the first part, the attention will be focused on the most common parameters used to describe the performance related to bulk/volume sensing and to surface sensing or biosensing. The idea is thus providing the basis for an easier and direct performance comparison among the fiber-optic devices. In the second part, some examples of fiber-optic devices will be presented in order to draw attention on novel approaches, devices and technology platforms towards future “food for thoughts”. The topics will concern fiber grating biosensing, fiber-optic bilimetry and pH-metry, novel coupling method based on whispering gallery mode resonator, biosensing in general based on different physical phenomena (such as lossy mode resonance, surface plasmon resonance, Bloch surface wave) and, finally, special attention will be paid to devices for neurodegenerative diseases. In particular, the combination of fiber-optics-based technology with the deposition of thin film overlays, nanocoatings, and nanostructures will be deeply emphasized.
