Abstract
Optical waveguide surface plasmon resonance (SPR) sensors are presented which exploit the phenomenon of the resonant excitation of surface plasmon waves by guided modes of optical fibers and integrated optical waveguides. Theoretical analysis of the SPR waveguide sensing structures is based on the mode expansion and propagation method. The integrated optical waveguide SPR sensor is composed of an optical waveguide fabricated by the K+--Na+ ion exchange in a glass substrate and gold as a surface plasmon resonance overlayer. The optical fiber SPR sensor is realized on a side-polished single-mode optical fiber which is locally coated with a thin gold film. Experimental study of the realized samples of the sensors has shown that variations in the refractive index of the sensed medium below 5X10-5 can be resolved with the sensors.
