General Approach for the Sensitivity Analysis and Optimization of Integrated Optical Evanescent-Wave Sensors [PDF]
, 2014 The optimization of integrated optical evanescent-wave sensors is dual. For optimal performances, we require waveguides with both maximal sensitivity to the measurand, the quantity intended to be measured, and minimal sensitivities to perturbations.
