AbstractMetallo-dielectric photonic crystals are sharp thermal emitters at infrared wavelengths, and are being employed in sensors. We describe the theory of thermal emission and enhanced absorption in these photonic crystals using a scattering matrix approach, where Maxwell's equations are solved in Fourier space. A sub-wavelength hole array in a metal layer is coupled to a two-dimensional photonic crystal of the same periodicity in these metallo-dielectric photonic crystals. The sub-wavelength hole array has an enhanced transmission mode that couples to a weakly guided mode of the photonic crystal having similar modal character. The transmissive mode of the hole array is absorbed by the photonic crystal to create a sharp absorption and reflective minimum. The enhanced absorption is investigated in different lattice symmetries.

Thermal Emission Spectrum

Thermal emission control with nanostructures has attracted considerable attention because of its potential applications in thermophotovoltaic (TPV) devices [1–3]. The optical-to-electrical conversion in a TPV system is driven by photons with energy higher than the electronic bandgap of the photovoltaic cell. A narrow-band emitter with emission spectrum slightly above the bandgap is ideal, which maximizes the conversion efficiency as well as minimizes the waste heat that deteriorates the performance of the cell. Specially designed nanostructures alters the band structure of photons in much the same way as the crystal lattice does on electrons inside semiconductors, thus changing the thermal emission spectrum. By employing nanostructure-enabled emission control, Lin, et al, projected an efficiency of 34% for TPV systems [2].
