Higher efficiency solar cells are needed to reduce solar array mass, volume, and cost for Air Force space missions. Intermediate-band quantum-dot (QD) solar cells can yield dramatically higher efficiencies than current multi-junction (MJ) technologies. However, several issues must be addressed to demonstrate manufacturable, high efficiency devices. CFDRC aims to develop: 1) High-efficiency, ligh ...

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 ...

Industrial Control Systems (ICS) are critical elements in electrical, water, oil/gas, and manufacturing services involving supervisory control and data acquisition (SCADA), distributed control systems (DCS), and programmable logic controllers (PLCs). These systems allow operators to monitor sensor data and remotely control field devices. Initially, these devices were designed for closed-network or ...

Nonlinear transmission lines offer new vistas in the generation of high power microwave wave (HPM) signals. All electromagnetic sources use an active medium to convert electrical energy to high frequency waves and ultra-wide band signals that can perform useful work. Traditional methods rely on electron beams for the active medium. Nonlinear transmission lines use nonlinear circuit elements to ...

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 ...

An eye-safe optically pumped laser based on a gas-filled hollow optical fiber will be demonstrated to lase at both near infrared (IR) and mid IR wavelengths. These lasers will be the first in a new class of IR lasers, based on the combination of hollow-f

To build a more intelligent grid, electric utilities must now construct a new architecture from connected, standard technologies. This smart architecture will connect SCADA systems so they can interact more efficiently. It will employ distributed monitoring and power-use optimization. It will also connect SCADA networks to corporate networks, wireless systems, and remote monitoring stations. ...

Inlustra Technologies and the University of Notre Dame propose a Phase I STTR program that, combined with a subsequent Phase II effort, will result in methods for the scalable production of semi-insulating non-polar GaN substrates. These substrates will be utilized in the fabrication of high-power/high-frequency AlGaN-GaN electronic devices capable of reliable operation under high thermal load. ...

Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

In response to SBIR topic MDA09-T006, USCI proposes to develop the first medium-level integrated circuit for radiation-tolerant applications. The advanced integrated circuit will be demonstrated based on a novel yet simple design SiC transistor that has the potential to provide a factor of 10X improvement in performance comparison to state-of-the-art. The SiC transistor can be fabricated by a subs ...
