Abstract
A fiber-optic surface plasmon resonance sensor may include an optical fiber and a surface plasmon excitation layer. The optical fiber may include a core, a cladding surrounding the core, and a depression. The surface plasmon excitation layer may include a first excitation layer, a second excitation layer and an optical waveguide layer between the first excitation layer and the second excitation layer. Incident light incident through the core may be coupled to the surface plasmon excitation layer at a specific angle of incidence and wavelength satisfying the surface plasmon resonance condition. Depending on the polarizing direction of the incident light, an s-polarized component may be coupled to the guided-wave mode in the optical waveguide layer constituting the surface plasmon excitation layer.
