A multi-scale/multi-physics software tool will be developed to predict manufacturing-induced defects, specifically void evolution during composites manufacturing, due to materials, parts, tooling and process parameters. Appropriately modeling the manufacturing process to identify potential problem areas will enable process optimization to produce structural components without defects. Specifically ...

Under the proposed effort, PSI will continue to develop a novel pmmW imaging technology developed under a prior Navy program to realize dense form factor arrays. This technology is based on an optical upconverted distributed aperture technology that can make large effective apertures in low SWaP form factors thereby maximizing achievable resolution. This sensor technology has already reached TRL 6 ...

In phase II work, we will collaborate with Prof. Dennis W. Prather in UD and continue to develop broadband, low VÏ€, high linearity, thin-film lithium niobate on insulator (LNOI) modulators that are fully compatible with silicon photonic integrated circuits (PIC) foundry processes. We will demonstrate a low VÏ€, broadband, small footprint LNOI modulator with hybrid Si/LN or SiN/LN waveguide ...

In phase II work, we will collaborate with Prof. Stefan Preble in RIT and continue to develop large scale hybrid integration and packaging techniques for key active photonic components such as lithium niobate on insulator (LNOI) modulators and modified uni-traveling (MUTC) photodiodes. We will demonstrate a low V, broadband, small footprint LNOI modulator with hybrid Si/LN or SiN/LN waveguide usin ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards a more integrated design approach that efficiently utilizes all available space. In fact, to accommodate limited space constraints many commercial off-the-shelf (COTS) systems will need to be replaced by custom designed and fabricated components. For radiofrequency (RF) electronic systems, this will requ ...

In this SBIR effort we will develop a balanced detection analog photonic link consisting of a DFB laser, a dual-output high-speed, low-Vp mach-zehnder modulator (MZM) and a high-power, high-linearity balanced photodetector (BPD) using a dual-core, single mode, multicore fiber (MCF) that is supplied by our subcontractor, OFS. We will design, fabricate and characterize (phase I) the MZM and the BPD, ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards more integrated platforms that utilize all available space. For radiating systems, this will require exploring innovative design methods, materials and manufacturing approaches to realize cost-effective, customizable and conformal antennas. An attractive solution to this challenge is offered by additive ...

Developers of modern software, particularly those targeting mobile or embedded platforms, are presented with a wide variety of hardware choices. Solutions can be built on microprocessors (e.g. x86, ARM, or Power architecture), GPUs (e.g. NVIDIAs Tegra), DSPs, FPGAs, or some combination of these technologies. Not only does this place a significant burden on programmers in understanding the intricac ...

With today's IRLED devices, >99.4% of input electrical power is converted into parasitic/waste heat. Moreover, as the local temperatures of the pixels increase due to the generated heat, IRLED optical efficiency is further reduced. Overall this severely limits the number and intensity of array pixels that can be simultaneously operated at high apparent temperatures. In Phase 2, we focus on develop ...

The Army is frequently forced to operate in hostile climates. Heavy fog, rain, snow, and dust storms can inhibit the performance of tracking technologies such as mid-wave infrared cameras. In such conditions, Army early warning systems are blinded and put personnel and assets at risk.There is a specific need for a degraded visual environment (DVE) penetrative target tracking solution.Radio frequen ...
