Abstract
A back-illuminated photo detector array (PDA) includes a front side and a back side. The back side receives optical energy incident on the back side at an incident direction. The front side includes a detection layer that includes detection structures and a plurality of photon-trapping nanostructures (PTN). The PTN cause optical energy incident on the back side to disperse in a direction perpendicular to the incident direction, and thereby improve an absorption efficiency of the back-illuminated PDA.
