Linewidth narrowing in silver-coated fiber surface plasmon resonance sensors through waveguide-structure-dependent modal regulation

Broad resonance dips limit the spectral resolution and figure of merit (FOM) of wavelength-interrogated fiber surface plasmon resonance (SPR) sensors. Here, silver-coated no-core fiber (NCF), multimode fiber (MMF), and hollow-core fiber (HCF) probes were compared under matched se...
