Abstract

We analyze the mid-infrared emission resulting from the interplay between a type-II superlattice (T2SL) material and semiconductor-based plasmonic “designer metals”. We demonstrate an order of magnitude emission enhancement, accompanied by spectral reshaping, relative to all-dielectric T2SL counterparts and provide a theoretical description of the underlying physics. The all-semiconductor LWIR emitters with integrated plasmonic components, developed in this work, represent novel approach to broadband room-temperature mid-IR sources.
