Sub-wavelength gratings are used in the new photodetector in this paper. The detectivity is enhanced by excitation of surface plasma waves (SPW) using a Metal Aperture Arrays grating. Sub-wavelength dielectric grating is used to replace the top Bottom Distributed Bragg Reflectors(DBR).
In this work new method for diffraction grating formation are suggested. This method allows to produce periodically corrugated thin metal films with transmittance strongly depends on the mutual correlation of two metal film interfaces with air and semiconductor. This could be the final stage of manufacturing of this type photodetector when all elements and circuits on the chip (like CCD matrix) are...
