We present optimized aperiodic structures for use as broadband thermal incandescent emitters which are capable of increasing the emittance by nearly a factor of two over the visible wavelength range when compared to bulk tungsten. These aperiodic multilayer structures are designed with alternating layers of tungsten and air or tungsten and silicon carbide on top of a tungsten substrate. We investigate the properties of these structures for use as lightbulb filaments. We find that these…

Equilibrium temperature of a spectral selective solar light absorber with angular dependent thermal emissivity

We develop an angular dependent thermal emissivity model by using the directional radiation pattern of short dipole antennas randomly oriented on a surface to predict the maximally achievable

Tailoring high-temperature radiation and the resurrection of the incandescent source.

A plain incandescent tungsten filament surrounded by a cold-side nanophotonic interference system optimized to reflect infrared light and transmit visible light for a wide range of angles could become a light source that reaches luminous efficiencies surpassing existing lighting technologies, and nearing a limit for lighting applications.

Optimized aperiodic highly directional narrowband infrared emitters

Bulk thermal emittance sources possess incoherent, isotropic, and broadband radiation spectra that vary from material to material. However, these radiation spectra can be drastically altered by

Strong self-dressing of the atom by its own localized radiation field leads to anomalous Lamb shifts and a splitting of the excited atomic level into a doublet when the transition frequency lies near a photonic band edge.
