Journal ArticleDOI
Myths and rumours of silicon photonics
Tom Baehr-Jones,Thierry Pinguet,Patrick Lo Guo-Qiang,Steven Danziger,Dennis W. Prather,Michael Hochberg +5 more
TL;DR: In this article, Hochberg et al. explain that the situation is much more complex in reality than low-cost manufacturing, high yields and seamless on-chip integration with electronics are often touted as the guaranteed benefits of silicon photonics, but is this really the case?
Journal ArticleDOI
Modified Compact Antipodal Vivaldi Antenna for 4–50-GHz UWB Application
TL;DR: In this article, a novel way capable of improving low-frequency performance of traditional Vivaldi antennas is presented, which is modified via introducing the loading structure, i.e., circular shape-load or slot-load, to match the termination.
Journal ArticleDOI
Thin film solar cell design based on photonic crystal and diffractive grating structures.
James G. Mutitu,Shouyuan Shi,Caihua Chen,Timothy Creazzo,Allen Barnett,Christiana B. Honsberg,Dennis W. Prather +6 more
TL;DR: Novel light trapping designs applied to multiple junction thin film solar cells incorporate one dimensional photonic crystals as band pass filters and nano structured diffractive gratings that cut into the photonic crystal layers are incorporated to redirect incoming waves and hence increase the optical path length of light within the solar cells.
Journal ArticleDOI
Dispersion-based optical routing in photonic crystals.
Dennis W. Prather,Shouyuan Shi,David Pustai,Caihua Chen,Sriram Venkataraman,Ahmed Sharkawy,Garrett J. Schneider,Janusz Murakowski +7 more
TL;DR: Self-collimation in planar photonic crystals is presented and experimentally validate as a new means of achieving structureless confinement of light in optical devices and the ability to arbitrarily route light by exploiting the dispersive characteristics of the photonic crystal is demonstrated.
Journal ArticleDOI
Radiofrequency signal-generation system with over seven octaves of continuous tuning
Garrett J. Schneider,Janusz Murakowski,Christopher A. Schuetz,Shouyuan Shi,Dennis W. Prather +4 more
TL;DR: In this article, a sideband injection-locked laser is used to generate low-noise, high-frequency radio signals that can be tuned over the range of 0.5-110 GHz.
