Journal ArticleDOI
Wide-angle infrared absorber based on a negative-index plasmonic metamaterial
TL;DR: In this paper, a PIMNIM that is subwavelength in all three dimensions enables absorption close to 100% for incidence angles up to 45° to the normal, and a specific implementation of such frequency-tunable PIMM based on plasmonic metamaterials is presented.
Journal ArticleDOI
Reaching the Nonlinear Regime of Raman Amplification of Ultrashort Laser Pulses
W. Cheng,Yoav Avitzour,Yuan Ping,Szymon Suckewer,Nathaniel J. Fisch,Min Sup Hur,Jonathan Wurtele +6 more
TL;DR: In this paper, the intensity of a subpicosecond laser pulse was amplified by a factor of up to 1000 using the Raman backscatter interaction in a 2 mm long gas jet plasma.
Proceedings ArticleDOI
Ultra-thin wide-angle perfect absorber for infrared frequencies
TL;DR: In this article, a two dimensional design of an ultra-thin, wide-angle perfect absorber for infrared light is proposed, which is shown to exhibit nearly 100% absorption at the resonant wavelength that is tunable by adjusting its geometric parameters.
Journal ArticleDOI
Characterization of the electrical properties and thickness of thin epitaxial semiconductor layers by THz reflection spectroscopy
TL;DR: In this article, the authors measured the dielectric properties and thickness of thin semiconductor epitaxy layers by the reflection of THz radiation from the surface of a two-layered semiconductor wafer.
Journal Article
On representing and correcting wavefront errors in high-contrast imaging systems
TL;DR: In this article, the authors show that conventional phase conjugation is not able to achieve the dark nulls needed for high-contrast imaging and present an alternative optimized solution for the shape of the deformable mirror based on the Fourier decomposition of the effective phase and amplitude aberrations.
