Wideband enhancement of infrared absorption in a direct band-gap semiconductor by using nonabsorptive pyramids

Efficient trapping of the light in a photon absorber or a photodetector can improve its performance and reduce its cost. In this paper we investigate two designs for light-trapping in application to infrared absorption. Our numerical simulations demonstrate that nonabsorptive pyramids either located...
