"This SBIR Phase I proposal addresses a need for improved UV and deep UV filters for aerospace and defense applications. A new approach to the design and fabrication short pass filters, based on a new photonic material, will allow filters to be made withtransmission at wavelengths as short as 130nm or less. Both these properties are unachievable by any other means. In Phase I, it is proposed to ...

"Stoichiometric Lithium Tantalate crystal (SLT: 50/50) was found to be overwhelmingly superior over its congruent counterpart (CLT: 48.75/51.25) in nonlinear optical, electro-optical (EO), UV transparency, and domain reversion. Third harmonic generation viaperiodically poled structure inside this SLT crystal is expected to be more efficient, and to be more realistic for fabricating novel compact U ...

"Optical computation requires very specific optical interconnection schemes such as the in-plane sharp bends and the fast channel switching functions. The integration requirement with existing waveguide technologies further put many limitations on using thecurrent technologies to develop such a device with acceptable performances. This project proposes a new concept of using a new bistable mechan ...

"Mid¿ is proposing a novel and innovative strain-sensor-grid using pseudoelastic shape memory alloys. By embedding a grid of ultra-thin pseudoelastic wires in an epoxy and encapsulating the embedded grid between two layers of Kapton, the embedded sensorcan be used as a layer in a composite, thus forming a multi-functional structure. When one of the Kapton layers is replaced with a flex-circuit ...

"Hypervelocity missiles are currently dependent on the deflection of aerodynamic surfaces for flight control. These deflections and surfaces contribute significantly to the drag of the missile. By eliminating these surfaces it is estimated that anincrease of up to 30 % in speed of kinetic energy penetrators can be achieved.Mid¿ proposes to investigate the use of precisely controlled, fast actin ...

"A novel method of micro-mixing by inducing a low frequency resonant sonic vibration (LFRSV) in the fluid medium results in the increased rate of energy dissipation per unit mass of the fluid, allowing rapid and efficient dispersion of solids, gases, andimmiscible liquids. This enhanced way of achieving micro mixing, can be used for dispersing nano particles in making gel propellants. Rheologica ...

"New bistable organic infrared (IR)-absorbing materials with extremely intense absorbance and reflectance across the entire 1300 to 1700 nm optical band and with picosecond-speed reversible switching to a non-absorbing and non-reflecting state are exploitedto make sub-wavelength (less than 1.5 microns) optical components for integration into optoelectronic transmitters. Both switching states are ...

OPTICAL COMPUTERS ARE RECOGNIZED AS POTENTIALLY USEFUL ELEMENTS IN THE QUEST TO MEET THE INTENSE BATTLE MANAGEMENT COMPUTATIONAL REQUIREMENTS OF THE SDI PROGRAM. CURRENTLY, OPTICAL COMPUTERS ARE GREATLY LIMITED IN PERFORMANCE BECAUSE NO EXISTING NONLINEAR LIGHT MODULATION DEVICE SIMULTANEOUSLY OFFERS FAST OPTICAL SWITCHING WITH HIGH GAMMA (THRESHOLD), HIGH SPATIAL BANDWIDTH, LOW POWER DISSIPATION, ...
