Abstract

Inhibited-Coupling Hollow-Core Photonic-Crystal Fibers (IC-HCPCFs) emerge nowadays as important candidates to the development of the new state-of-the-art in fiber optics. The recent demonstrations on their performances and their wide application panorama entail great interest from the scientific community. In this context, this project proposes the development of IC-HCPCF-based devices and sensors, namely the application of IC-HCPCFs as a platform for Power-over-Fiber (PoF), the characterization of materials with technological interest (two-dimensional materials), and the development of optical sensors. The realization of PoF using IC-HCPCFs is possible thanks to the fact that, in IC-HCPCFs, the optical mode propagates through the fiber with minimal interaction with the fiber microstructure. Thus, IC-HCPCFs can withstand the transmission of more powerful beams comparatively with standard optical fibers. It is expected, therefore, that the research efforts under the scope of this project will allow demonstrating the first realization of an IC-HCPCF-based PoF platform (a proposition which reveals itself as innovative and that has not been reported in the literature yet). Concerning the characterization of two-dimensional materials and the development of sensors, this project proposes to explore the IC-HCPCFs capability of acting as a micro-reservoir and a waveguide simultaneously. The activities proposed herein will encompass the characterization of low-concentration two-dimensional materials solutions and the demonstration of optical sensors allying IC-HCPCF to upconverting nanoparticles (UCNPs), whose emission spectrum can be sensitive to the variations of parameters of interest (e.g., magnetic field variations).
