Plasmonic enhanced ultrafast switch.
Abstract
Ultrafast electronic switches fabricated from defective material have been used for several decades in order to produce picosecond electrical transients and TeraHertz radiation. Due to the ultrashort recombination time in the photoconductor materials used, these switches are inefficient and are ultimately limited by the amount of optical power that can be applied to the switch before self-destruction. The goal of this work is to create ultrafast (sub-picosecond response) photoconductive switches on GaAs that are enhanced through plasmonic coupling structures. Here, the plasmonic coupler primarily plays the role of being a radiation condenser which will cause carriers to be generated adjacent to metallic electrodes where they can more efficiently be collected.

A study of plasmonic enhanced transmission effects in nano-optics
This project was a numerical study of the behavior of surface plasmons in nano-systems, focusing on the interaction between plasmons, light, and nano-scale structures such as nano-scale metallic wires and quantum wires/dots. The primary results of the project included: a) the demonstration of the use of surface plasmons to modify the spatial coherence of a light wave, b) the demonstration of a feasible plasmonic superresolved readout system, and c) the demonstration of a Plasmonic Zeno effect, in which the attenuation of a light wave in metal is suppressed by breaking up the metal into a collection of structured layers.

4 ESS (trademark) switch electromagnetic-pulse assessment. Volume 2. Task 3 laboratory testing of the 4 ESS Switch. Final report
The 4ESS Switch was subjected to test sequences representative of electromagnetic stresses following a high-altitude nuclear blast. These laboratory tests revealed some potential equipment sensitivities requiring only minor modifications. With these modifications implemented, the 4 ESS Switch demonstrated considerable robustness in servicing calls following current injection stress. (jhd)
