Journal ArticleDOI
Plasmon dispersion relation of Au and Ag nanowires
Gerburg Schider,Joachim R. Krenn,Andreas Hohenau,Harald Ditlbacher,Alfred Leitner,Franz R. Aussenegg,William L. Schaich,Irina Puscasu,Brian Monacelli,Glenn D. Boreman +9 more
TL;DR: In this paper, surface plasmon modes on silver and gold nanowires of a fixed cross section and different lengths, produced by electron beam lithography were determined by extinction spectroscopy and can be interpreted in terms of standing Plasmon polariton waves.
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.
Journal ArticleDOI
Narrow-band, tunable infrared emission from arrays of microstrip patches
Irina Puscasu,William L. Schaich +1 more
TL;DR: In this article, a combination of theory and experiment is used to demonstrate that an array of microstrip patches leads to a surface with sharp and tunable emission bands, and the physical mechanisms and locations for various emission peaks are described via both analytical theory and numerical simulations.
Journal ArticleDOI
Improving solar cell efficiency using photonic band-gap materials
Marian Florescu,Marian Florescu,Hwang Lee,Irina Puscasu,Martin U. Pralle,Lucia Florescu,Lucia Florescu,David Z. Ting,Jonathan P. Dowling +8 more
TL;DR: The potential of using photonic crystal structures for realizing highly efficient and reliable solar-cell devices is presented in this paper, where photonic crystals emerge as one of the leading candidates for frequency and angular-selective radiating elements in thermophotovoltaic devices.
Journal ArticleDOI
Extraordinary emission from two-dimensional plasmonic-photonic crystals
Irina Puscasu,Martin U. Pralle,Martin McNeal,James T. Daly,Anton C. Greenwald,E. Johnson,Rana Biswas,C. G. Ding +7 more
TL;DR: In this paper, the authors exploit the interaction between surface plasmons at a metal interface with a photonic crystal in silicon to control the spectral response of the surface in reflection, absorption, and emission.
