Abstract

We have a light detector structure based on plasmonic effects for maximum light absorption at a wavelength of 820 nm have suggested and the two-stage absorption rate to have increased considerably compared to the previous ones Firstly by placing layers of glass between gold and the semiconductor GaAs is Grating and secondly embedding silver nanoparticles in the metal Grating gold With the implementation of each stage can be seen to increase light absorption in the detector in this structure we proposed for the first time we ve done it both ways to intensify the absorption coefficient is 25 83
