Abstract
This Letter theoretically proposes and investigates an integrated plasmonic sensor that is based on a grating-assisted coupling between a surface plasmon polariton (SPP) and a dielectric waveguide (DW) mode. It consists of a glass slide with a gold film for the propagation of an SPP and a separate DW with a long-period grating. For sensing, the two parts are temporarily combined. After sensing, the former is replaceable, and so the sensor has disposability. The design procedure and analysis method for the sensor are explained. The designed sensor is shown to be very compact. Its characteristics of sensing a change of the refractive index of liquid are analyzed and discussed.
