Abstract
A photodetector focal plane array (FPA) with enhanced detection capability and reduced thermal current is provided. The FPA includes light-concentrating dielectric structures in a form of arrays of elements with three-dimensional geometrical shapes. The elements have tapered sidewalls that taper inwardly toward a surface portion with a reduced width. A photodetector is joined to the portion with a reduced width. A metallic layer is disposed over the tapered sidewalls of the elements and the portion of the surface of the elements with a reduced width. The metallic layer provides mirror reflection properties to concentrate electromagnetic fields towards the detectors. The photodetector focal plane array may be used for infrared (IR) imaging applications in mid-wave IR (MWIR) and long-wave IR (LWIR) cameras as night vision and thermal imaging devices.
