Abstract

We consider optimized configurations of high-contrast one-dimensional sub- wavelength gratings as label-free biosensors for proteins detection. Parameters of the sen- sors, in particular sensitivity, are improved in comparison with the basic design. Modeling was done by three numerical methods providing required reproducibility and convergence.
