This proposal describes a new communication device that can provide information from remote sensors through modulated retro-reflection using an active optical mirror. Through the integration of optical micro-electromechanical (MEMS) devices, high speed, low power electronics, and high precision corner cubes the project team will be able to demonstrate a modulating retro-reflector that can transmi ...

We propose to develop and fabricate an optical scanner required to address a 2-D array of trapped Rubidium atomic qubits with two lasers simultaneously. One of the most scalable approaches to quantum information processing (QIP) is Optical addressing of arrays of trapped atoms. This is done with focused spots using tuned lasers which program initial states and implement 2-quibt gates. High spatial ...

It is the purpose of this Phase I STTR program to both demonstrate proof of concept of long nanotubes as receiving and transmitting microwave antennas, and to develop detailed simulation tools to predict their performance and determine the optimum geometry. This will build on four years of UC Irvine experience fabricating mm long individual single walled carbon nanotubes, and pioneering theoretica ...

Optical retro-reflectors have been used for communications for many years. The approach has many advantages, when one terminal has limited power, space, weight, and a low cost as requirements. The major limitation for “Retro-Comms” has been that the modulator consumes too much power at higher modulation rates. What we propose is to reduce the power, size, weight and cost of the Retro-Modula ...

Inlustra Technologies and the University of California, Santa Barbara propose to grow and characterize thick non-polar and semi-polar gallium nitride (GaN) wafers that will act as seeds for subsequent GaN boule growth. In this Phase I STTR effort, Inlustra will first develop non-polar and semi-polar GaN films with smooth surfaces and minimal wafer bowing and cracking. The growth conditions for e ...

This effort will culminate in the demonstration of a new class of antennas, to allow the coupling of RF signals with nanoscale devices and sensors. An antenna for RF must be millimeters long, and nanoscale in diameter, if it is to interact with nanoscale devices. The aligned carbon nanotubes grown at NanoLab are synthesized in millimeter lengths, have good conductivity, and therefore should make ...

The purpose of this project is to demonstrate the effectiveness of using an innovative deposition process for making Sm2Fe17Nx/á-Fe16N2 magnetic materials in bulk quantities. In addition, exchange-coupled nanostructured composites of these materials will be produced. The advantage of this process is that it allows precise control over the deposition ions so that the morphology of the materials ca ...

The problem of detecting hazardous trace species rapidly and sensitively is a difficult spectroscopic problem. Potentially, this problem might be solved with an elemental detection method such as LIBS combined with a molecular detection method. Laser-induced fluorescence (LIF) might be a candidate for the detection of small molecules, but for larger polyatomic molecules, the resulting fluorescence ...

We propose a comprehensive and innovative approach for analysis and visualization of large, complex, multi-step cyber attack graphs. First, we select the radial space-filling hierarchy visualization module for large complex multi-step cyber attack graph due to its strengths in space efficiency and ease of interpretation. Once an attack is correlated, the attack notification service retrieves the ...

We propose a new method developed by our employees and collaborators for the digital representation of real world objects. This will result in an implicit surface urban terrain model that interpolates raw point cloud data. The method can handle complex topologies and geometries easily. Topology changes pose no difficulties. The key idea involves shrink wrapping an implicit surface around data poin ...
