Abstract

The integration of grating diffraction and transport-equation was carried out to improve efficiency and fastening response of photodetectors. It was shown numerically that to increase the efficiency when working with non-zero diffraction orders, the depletion region should be placed into the grating grooves. In the carrier-transport part, analytic results for simple geometry were used and simulation was performed using MATLAB® PDE Toolbox for two-dimensional (2D) field geometry. The results show that if the absorption region is apart of grating the depletion-operation mode is always less efficient than the diffusion-operation.
