Metamaterial Emitter Research Highlighted in Nature Photonics
A metamaterial light source recently developed at the IEF is highlighted in the June issue of Nature Photonics.
The journal Nature Photonics features the metamaterial thermal light source recently developed at the IEF in a “Research Highlight” in its latest issue (June 2017) [1]. In contrast to conventional thermal emitters, the metamaterial light source emits a very narrowband spectrum in the mid-infrared wavelength range with high efficiency [2]. Thus, additional filter elements in a gas sensing system become obsolete, which enables for compact sensing systems. Due to its compatibility with standard fabrication processes, the novel light source allows for a new generation of highly integrated, low power and low cost gas sensors.
