Such high enhancement is attributed to resonant interference of surface plasmon modes at the metal-semiconductor interface. Horizontal surface plasmon modes were reported earlier to inhibit photodetector performance. We computationally show, however, that horizontal modes enhance the efficiency of surface devices despite reducing transmitted light in the far field.EnglishPhotodetectorsPlasmonsSilicon germaniumAbsorption enhancementFar fieldHorizontal surfacesMetal semiconductor interfaceMetal semiconductor metalMetal semiconductor metal photodetectorMetallic nanoslit arraysNanoslitsOptical detectorsPlasmonicSilicon germaniumSurface deviceSurface plasmon modesTransmitted lightGermaniumPhotodetectorsPlasmonsArticle10.1109/LPT.2012.2183342
