A novel sensing approach has been presented. The Surface Plasmon Resonance (SPR) and the properties of multimodal plastic optical fibers (POFs) have been used to implement this novel approach. For instance, the proposed sensor systems harnessing this method have been designed, realized, and tested to detect a magnetic field, temperature, and force. More in detail, the physical quantity under test interacts with a sensitive patch (a modified multimode POF), changing the light mode profile at the input of an SPR-POF platform combined with a dielectric medium at a fixed refractive index. This method allowed to use of the SPR platform without any additive sensing layer, obtaining very interesting results compared to the traditional plasmonic sensing approach.

Abstract
A novel sensing approach has been presented. The Surface Plasmon Resonance (SPR) and the properties of multimodal plastic optical fibers (POFs) have been used to implement this novel approach. For instance, the proposed sensor systems harnessing this method have been designed, realized, and tested to detect a magnetic field, temperature, and force. More in detail, the physical quantity under test interacts with a sensitive patch (a modified multimode POF), changing the light mode profile at the input of an SPR-POF platform combined with a dielectric medium at a fixed refractive index. This method allowed to use of the SPR platform without any additive sensing layer, obtaining very interesting results compared to the traditional plasmonic sensing approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
