Abstract
An integrated optical sensor based on the resonant coupling between a surface plasmon wave and a guided mode of an integrated optical wavegu ide is reported. Detailed theoretical analysis of the proposed sensor based upon the modal approach and upon the mode expansion and propagat ion method is presented. The performance of a realized sample of the w aveguide sensor is investigated. Et is demonstrated that by measuring the optical power transmitted through the sensing element, variations in the refractive index of the analyte as small as 2 X 10(-5) may be r esolved.
