Silver nanoparticles grown in nanochannels of anodic aluminum oxide on a grating form a surface-enhanced Raman scattering (SERS) substrate with the double resonance from both localized and delocalized ...

The novel concept employs a long-period fiber grating (LPG) to achieve surface plasmon resonance (SPR) of a single cladding mode at the gold-coated tip of a single-mode fiber. The sensor combines a ...

Abstract: A liquid level sensor based on a fiber Bragg grating (FBG) assisted by a section of multimode fiber core (MMFC) was demonstrated. Since the coupling coefficients between the MMFC and the ...
