Abstract

An optical fiber sensor for absorption studies based on surface plasmon resonance (SPR) interrogation in the wavelength domain is proposed. The SPR wavelength is measured with high resolution which makes it possible to detect very small changes in SPR owing to the absorption of molecules onto the sensing surface. As a model case, the absorption of water molecules on silicon dioxide was studied experimentally.
