Future gas turbine propulsion designs, in addition to incorporating variable geometrical engine features, will require controlling and integrating large power generation/extraction, as well as, managing thermal limits of the components. The engine contro...

allowing the sensitive RF front-end to be located away from the now more compact phased array antenna. We are proposing a rugged photonic integrated spatial division multiplexing RF link for phased array system with low cost, size, weight and power cons...

Next-generation intelligent engines will operate at higher temperatures for increased efficiency and will migrate from centralized to distributed control. There is critical need for sensors for operation at ultra-high temperatures (3000F). Conven...

Advanced infrared imaging techniques are of great interest but associated high costs of III-V and II-VI SWIR and MWIR materials prohibit their widespread deployment and integration with other optoelectronic devices. Freedom Photonics and its team partner...

This proposal describes the development of a process to synthesize low defect Ge1-xSnx and SiyGe1-x-ySnx layers on silicon and silicon-on-insulator (SOI) substrates through low thermal budget excimer laser and rapid thermal annealing/crystallization for ...

Molecular beam epitaxy has become essential technique to produce high quality materials and complicated structures. Competing with other growth techniques, such as MOCVD, it has demonstrated higher materials quality and better film uniformity. These adva...

ABSTRACT: Digital binocular helmet-mounted display (HMD) systems are now available that allow high resolution wide field-of-view (WFOV) digital imagery to be displayed on high resolution microdisplays. These digital HMD systems require a low-latency embedded vision processor (LLEVS) capable of implementing the necessary image processing algorithms. An SA Photonics LLEVS will be implemented on next ...

We propose a new fiber WDM fabrication method for single mode high power fiber laser. Our new approach will enable kW operation for both single mode fiber WDM and PCF WDM. In Phase I, a proof of concept experiment has been demonstrated. In phase II, we will target at delivery of a reliable prototypes for both step index fiber WDM and PCF WDM.

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

The ability of Large-eddy simulation (LES) techniques to accurately predict combustion instabilities and the onset of lean blow-out is not yet firmly established, especially in realistic operating conditions. A number of modeling choices play an importan...
