Abstract:
The present invention provides an optical detector device, including: a metal absorber layer; and a dielectric cover layer coupled to the metal absorber layer, wherein the dielectric cover layer includes one or more antireflective structured surfaces. The optical detector device further includes one or more of a passive substrate layer and an active thermoelectric element layer coupled to the metal absorber layer opposite the dielectric cover layer. The one or more antireflective structured surfaces each utilize a random pattern.
