Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

Thermal emission is a ubiquitous and fundamental process by which all objects at non-zero
temperatures radiate electromagnetic energy. This process is often assumed to be …

Incandescent filaments and membranes are often used as infrared sources despite their low
efficiency, broad angular emission, and lack of spectral selectivity. Here, we introduce a …

Incandescent sources such as hot membranes and globars are widely used for mid-infrared
spectroscopic applications. The emission properties of these sources can be tailored by …

Freestanding silicon nitride (Si N) mechanical resonators are of central interest in
applications such as temperature and mass sensing, and for fundamental optomechanical …

The development of novel thermal sources that control the emission spectrum and the
angular emission pattern is of fundamental importance. In this paper, we investigate the …

We introduce thermal metallo-dielectric metasurfaces as mid IR sources. The emitter is a
lossy metal. The spectral and angular emission is controlled using a periodic array of high …

There is today a growing need to accurately model the angular scattering response of
metasurfaces for optical analog processing applications. However, the current metasurface …

We report the design, fabrication and characterization of CMOS compatible metal-insulator-
metal (MIM) plasmonic resonators made of tungsten and silicon nitride for the mid-infrared …

Blackbody radiation is incoherent and omnidirectional, whereas various novel applications
in renewable energy require a degree of directional control of a thermally emitted beam. So …
