Journal ArticleDOI
A three-dimensional photonic crystal operating at infrared wavelengths
Shawn-Yu Lin,James G. Fleming,Dale L. Hetherington,Bradley K. Smith,Rana Biswas,Kai-Ming Ho,Mihail M. Sigalas,W. Zubrzycki,Steven R. Kurtz,J. Bur +9 more
TL;DR: In this article, the authors constructed a 3D infrared photonic crystal on a silicon wafer using relatively standard microelectronics fabrication technology, which showed a large stop band (10−14.5μm), strong attenuation of light within this band (∼12 dB per unit cell) and a spectral response uniform to better than 1 per cent over the area of the 6-inch wafer.
Journal ArticleDOI
Photonic band gaps in three dimensions: New layer-by-layer periodic structures
TL;DR: In this article, a 3D periodic dielectric structure with circular, elliptical, or rectangular shape is introduced. But the 3D layer structure can be easily fabricated using conventional microfabrication techniques on the scale of optical wavelengths.
Journal ArticleDOI
All-metallic three-dimensional photonic crystals with a large infrared bandgap
TL;DR: It is proposed that these 3D metallic photonic crystals can be used to integrate various photonic transport phenomena, allowing applications in thermophotovoltaics and blackbody emission.
Journal ArticleDOI
Photonic crystal enhanced light-trapping in thin film solar cells
Dayu Zhou,Rana Biswas +1 more
TL;DR: In this paper, photonic crystals were utilized to simulate enhanced light-trapping in a-Si:H thin-film solar cells, where a one dimensional photonic crystal or distributed Bragg reflector with alternating dielectric layers acts as low loss backreflector.
Journal ArticleDOI
Photonic crystal enhanced narrow-band infrared emitters
Martin U. Pralle,N. Moelders,M. P. McNeal,Irina Puscasu,A. C. Greenwald,J. T. Daly,E. A. Johnson,T. George,Daniel S. Choi,Ihab El-Kady,Rana Biswas +10 more
TL;DR: In this paper, a thermally stimulated mid-infrared source was developed that emits radiation within a narrow range of wavelengths (δλ/λ⩽0.2) defined by the periodicity of a metal coated silicon-air photonic crystal etched into the emitter surface.
