General approach for the sensitivity analysis and optimization of integrated optical evanescent-wave sensors

摘要: The optimization of integrated optical evanescent-wave sensors includes two parts. For optimal performance, we require waveguides with both maximal sensitivity to the measurand—the quantity intended be measured—and minimal perturbations. In this context, fully numerical approaches are extremely powerful but demand huge computer resources. We address issue by introducing a general and efficient approach, based on formal derivation analytical dispersion equations, express evaluate all waveguide sensitivities. particular, apply approach rectangular discuss its accuracy use within procedures.
