Improving the sensing capabilities of miniaturized probes nanofabricated on the tip of optical fibers is crucial for a large number of sensing applications in remote and harsh environ-ments. While most research efforts are directed towards developing improved fabrications techniques or more sensitive structures, we show that the performance of these sensors can be significantly enhanced by designing...
Optical fibers technology has experienced a tremendous growth and advancement over the past several decades, not only in transmission systems for communications (where nowadays totally dominate especially at the high performances level) but also in the sensing field [1]. For this reason, there is an ever increasing need to add new functionalities and improve the performances, through the integration...
We report the design, fabrication and characterization of a 2D hybrid metallo-dielectric photonic crystal (PC) nanostructure, directly realized by innovatively applying the electron beam lithography technique on the cleaved end face of a standard single mode optical fiber (SMF). In our configuration, the PC is illuminated in the out-of-plane direction and plasmonic-photonic resonances are excited...
