Mathematical simulation of nonlinear optical wave-guided sensors

Abstract

In this communication, we present an extensive theoretical analysis of nonlinear wave guide structure sensor and derive the conditions of the maximum sensitivity of TE nonlinear surface plasmons. The theoretical requirements for reaching high sensitivity of the proposed nonlinear waveguide sensor will be determined. Exact maximum sensitivity expressions for nonlinear surface plasmons in sensing schemes will be obtained, which will allow the designer to find the work basis of maximum sensitivity and to create the right dimensioning of the proposed structure. We believe that the theoretical predictions and numerical modeling could realize future versatile sensors. The above concepts could be experimentally demonstrated and carried out.
