Abstract

This paper presents a Surface Plasmon Resonance (SPR) fiber sensor capable of monitoring the deposition of thin nm-scale polymer films. The sensor was used for in situ monitoring of the adsorption of 30 mono-layers of oppositely charged polyelectrolytes with an overall thickness of each individual monolayer less than 0.55 nm. The in situ monitoring of the formation of multi-layer structures was implemented through the excitation of SPR on the surface of a gold-coated fiber with a Tilted Fiber Bragg Grating (TFBG) written in the core of the optical fiber.
