Abstract
In the past few years, there has been increasing interest in surface plasmon-polaritons, as a result of the strong near-field enhancement of the electric fields at a metal–dielectric interface. Here we show the first demonstration of a monolithically integrated plasmonic focal plane array (FPA) in the mid-infrared region, using a metal with a two-dimensional hole array on top of an intersubband quantum-dots-in-a-well (DWELL) heterostructure FPA coupled to a read-out integrated circuit. Excellent infrared imagery was obtained with over a 160% increase in the ratio of the signal voltage (Vs) to the noise voltage (Vn) of the DWELL camera at the resonant wavelength of λ=6.1 μm. This demonstration paves the way for the development of a new generation of pixel-level spectropolarimetric imagers, which will enable bio-inspired (for example, colour vision) infrared sensors with enhanced detectivity (D*) or higher operating temperatures. Infrared cameras are used for night vision and in medical diagnostics, but currently only present monochrome images. Krishnaet al. demonstrate a monolithically intergrated plasmonic infrared quantum dot camera as a step towards coloured infrared imaging.
