ABSTRACT: Based on our success in developing the world first commercial 10 W femtosecond fiber laser system and our leading technology development in ultrashort pulsed fiber laser and nonlinear fiber optics, PolarOnyx proposes, for the first time, a compact all fiber based high power (>500 mW) mid-IR supercontinuum source (3-12 micron) to meet with the requirement of the AF solicitation. The lase ...

The ever-decreasing size of the electronic microchips and the ever-increasing density of electronic components required to support future Air Force platforms are creating the problem of substantial localized heat generation that can impair component operation. State of the art thermal interface materials (TIMs), that are used to dissipate heat from the source to the spreader in a microchip, are se ...

MZA proposes design, integration, testing, and simulation of electro-optical (EO) imaging and computer processing hardware for operating a phased array consisting of 7-12 subapertures. Our implementation of image processing on a graphics processor units (GPUs) for subaperture piston control will be upgraded and computer hardware will be built in Phase II to operate at control rates exceeding 1 kH ...

Recent advances in dielectric and magnetic materials have spurred renewed interest in the field of solid state pulse and RF burst generation using Non-Linear Transmission Lines (NLTL) . The NLTL approach to HPM and UWB generation eliminates the need for an electron beam, vacuum system and magnets required in conventional HPM sources. Furthermore, the novel waveforms of NLTL generated pulses promi ...

We propose to develop ultradense plasmonic integrated devices and circuits for optical interconnect compatible with the electronic circuitry. In our proposal, we will employ engineered metallic nanostructures that combine energy concentration by plasmonic lenses and retardation-based plasmonic resonances to even further boost the efficiency of materials exhibiting optical nonlinearity. These plas ...

Combustion stability is an important consideration in the design of liquid rocket engines. While fundamental modes of unstable operation in simple geometries are easily identified using analytical methods, recent times have seen these methods greatly expand in scope, applied in semi-numerical format to increasingly complex geometries and flow situations. Much remains to be explored in understandin ...

The leakage of electromagnetic (EM) energy into air vehicles, and particularly into ordnance, poses a hazard that requires careful evaluation. Under current guidelines, such evaluations are primarily to be carried out through extensive testing of items under possible field conditions, a process that can be both time-consuming and costly. The scope of this STTR Phase I activity is to implement a h ...

The gap between research in numerical methods and popular commercial solvers in CFD and related areas has been gradually widening in the recent past, particularly in the realm of high order accurate algorithms. At HyPerComp we are advancing a suite of high order codes based on the discontinuous Galerkin (DG) technique that can be used in electromagnetics, fluid mechanics, MHD and radiative heat tr ...

Radiative heat transfer is a dominant mode of heat transfer in combustion and propulsion systems as well as for hypersonic flow encountered during planetary entry. Solution of the Radiative Transfer Equation (RTE), which is an integro-differential equation, places stringent requirements on the computational resources as: (a) the radiation depends both on spatial and angular dimensions, (b) radiati ...

Quantum cryptography, and in particular Quantum Key Distribution (QKD) is a secure method to distribute a secret key between two distant authorized partners whose security is based on the laws of physics. Current public key cryptosystems have not been proven to be secure and are based on the computational complexity of evaluating one-way functions. These functions are easily evaluated, but extrem ...
