Single-cycle gap soliton in a subwavelength structure

We demonstrate that a single sub-cycle optical pulse can be generated when a pulse with a few optical cycles penetrates through resonant two-level dense media with a subwavelength structure. The single-cycle gap soliton phenomenon in the full Maxwell-Bloch equations without the frame of slowly varying envelope and rotating wave approximations is observed. Our study shows that the subwavelength structure can be used to suppress the frequency shift caused by intrapulse four-wave mixing in continuous media and supports the formation of single-cycle gap solitons even in the case when the structure period breaks the Bragg condition. This suggests a way toward shortening high-intensity laser fields to few- and even single-cycle pulse durations.Comment: 4 pages, 6 figure

Self-consistent calculation of metamaterials with gain

We present a computational scheme allowing for a self-consistent treatment of a dispersive metallic photonic metamaterial coupled to a gain material incorporated into the nanostructure. The gain is described by a generic four-level system. A critical pumping rate exists for compensating the loss of the metamaterial. Nonlinearities arise due to gain depletion beyond a certain critical strength of a test field. Transmission, reflection, and absorption data as well as the retrieved effective parameters are presented for a lattice of resonant square cylinders embedded in layers of gain material and split ring resonators with gain material embedded into the gaps.Comment: 5 pages, 6 figure

Drilling Down: New York, Hydraulic Fracturing, and the Dormant Commerce Clause

The debate surrounding hydraulic fracturing and natural gas development from shale rock needs no embellishment. This highly sought resource and highly fought drilling technique trigger significant concerns: human health, energy independence, national security, water safety, air quality, agricultural well-being, outdoor aesthetic impairment, government involvement at all levels and by all branches, and economic development and sustainability. Whether actively participating in this conversation or not, everyone has a stake in the resolution of whether to allow this technique to be utilized and these resources to be produced
