We will develop a lab-on-chip optical absorption spectrometer spanning 3-15micron molecular fingerprint region, in a single epitaxially grown heterostructure that monolithically integrates thermally tuned distributed feedback quantum cascade laser (QCL) and quantum cascade detector (QCD) arrays with slotted photonic crystal waveguides (SPCWs) in a mid-infrared InGaAs passive photonic waveguide. In ...

Our nation’s warfighters require advanced armor to give them the best protection while allowing mobility to perform their missions. This proposal will develop two powerful tools to aid future body armor advancements. First, this research program will develop a statistical analysis software that will predict likelihood of impacts based on defined attack scenarios (i.e. rifle, distance and firing ...

Americas current electronic warfare (EW) capabilities are insufficient for the modern and future battlefield. To safeguard against radio-controlled threats and disrupt enemy communications, our current EW systems blindly jam broad swaths of the electromagnetic spectrum (EMS). This approach interferes with Blue Force data and voice communications, requires large power sources and generates distinct ...

Antimicrobial treatment of military textile systems is intended to provide enhanced protection to the Warfighter in the field by preventing colonization of harmful bacteria that cause various skin and soft tissue infections (SSTI) such as impetigo, boils, abscesses, cellulitis and life-threatening necrotizing fasciitis. Current treatments can impart antimicrobial functionality to textiles; however ...

Novel photonic structures, such as periodic metal-dielectric photonic bandgap structures (MDPBG) have the potential to revolutionize the field of optical windows. The large mismatch in the permittivities of the metal and dielectric creates resonant tunneling, which allows for high transmission in regions where metals are typically opaque. This property makes MDPBGs very attractive for screening or ...

Scanning probe microscopy (SPM) is a technique used to detect near-field interaction when a sample is rater-scanned by a probe. Example include atomic force microscope (AFM) and scanning tunneling microscope (STM). It offers nanometric and atomic image resolution. In this field, an emerging technique, Near-Field Scanning Microwave Microscopy (SMM), utilizes microwave evanescent waves to attain the ...

TransWave Photonics, LLC proposes to develop mid-wave infrared photonic integrated circuits based on monolithic integration of passive low-loss waveguides, thermo-optically tunable photonic elements, and quantum cascade gain sections within the same InGaAs/AlInAs/InP platform. The proposed approach will enable power combining and 2-dimensinoal beam steering of the outputs from multiple high-power ...

Integration of RF ferrites on printed circuit boards (PCBs) is highly desired for realizing compact, lightweight and low-cost systems with different RF ferrite components, including inductors, antennas and antenna arrays, etc. However, it has been challenging to integrate ferrites on PCBs. Spin spray deposition can produce fully dense, high crystalline quality, and low-loss RF ferrites at a low te ...

The NMR relaxometry instrument developed in Phase I project will be refined and thoroughly calibrated for nondestructive evaluation of the structure and properties of polymer-inorganic interfaces. The system design, operation conditions and data acquisition/analysis algorithms will be improved for precise and reliable evaluation of the structure and properties of the interfaces formed between dive ...

The Tunable Active HEterodyne Terahertz Imager (TAHETI) system will use Terahertz Quantum-Cascade Lasers (QCL) combined with a Schottky diode detector for ultra-high dynamic range heterodyne imaging. Distributed feedback (DFB) QCLs with milliwatt power levels are engineered to emit at slightly offset frequencies, and are used as local oscillator and illumination for imaging. The QCLs will be down ...
