Abstract

We demonstrate strong-to-perfect absorption across a wide range of mid-infrared wavelengths (5-12µm) using a two-layer system consisting of heavily-doped silicon and a thin high-index germanium dielectric layer. We demonstrate spectral control of the absorption resonance by varying the thickness of the dielectric layer. The absorption resonance is shown to be largely polarization-independent and angle-invariant. Upon heating, we observe selective thermal emission from our materials. Experimental data is compared to an analytical model of our structures with strong agreement.

Normal incidence reflection for two-layer metal-dielectric systems as a function of dielectric thickness. (a) A near-perfect electrical conductor coated in a low-loss, high index dielectric. Here the first reflection minimum occurs at d = λ/4n. (b) A finite conductivity metal with a lossy, high-index dielectric, with a reflection minimum at d<λ/4n. (c) The system most closely resembling the structures studied in this work, consisting of an engineered metal with plasma wavelength near the wavelength of the incident light in free-space, and a high-index, lossless dielectric. Such structures demonstrate strong absorption with d<λ/4n.

(b) Schematic of the sample structure investigated in this work and (c) sample structure used for the T-matrix model of this work. (d) Real (black) and imaginary (red) components of the extracted permittivity for the surface of the n + SOI wafer shown in (a).

(a) Modeled (solid black) and experimental (blue squares) reflection, and modeled absorption (solid red) from a n + doped SOI wafer coated with 165nm of germanium. (b) Schematic of the sample structure investigated in this work and (c) sample structure used for the T-matrix model of this work.

(a) Experimental and (b) modeled reflection (color scale) as a function of wavelength and germanium thickness. Anomalies in (a), at λ0≈4.2μm result from fluctuations in atmospheric absorption between our sample and background data, and are artifacts of the measurement.

Fig. 5
Fig. 5

Experimental (blue diamond) and modeled (blue line) scaling factor (SF) for our doped Si-Ge structures, showing the reduction in our Ge layer thickness from the thickness λ0/4n required for absorption resonances on traditional metals with low-loss dielectric coatings. Red line shows phase shift for reflection at the doped Si-Ge interface. As we move to longer wavelengths, the doped-Si begins to behave more like a perfect conductor, giving a phase shift approaching π.

Experimental (a,c) and modeled (b,d) reflection as a function of wavelength and angle for s-polarized (a,b) and p-polarized (c,d) incident light, for a sample with Ge thickness of d = 412.5nm.

Experimental (a) and modeled (b) thermal emission as a function of wavelength for doped silicon samples with germanium coatings of various thicknesses. The dotted line in (b) is the Planck blackbody spectrum AT 450K, modulated by the FTIR internal detector response. Inset shows thermal emission image from 425nm of germanium patterned to the University of Illinois logo.
