Reduced mass materials are critical to the success of aerospace systems. Thus, large air and space structures can benefit from lightweight composite materials. However, their adoption is impaired by the lack of a robust, cost-effective fabrication process, principally because the autoclaves used to consolidate composite laminates are so expensive for large parts. This program develops for US aeros ...

This SBIR Phase II effort proposes the development and integration of a Planar Lightwave Circuit (PLC) into an all fiber-based seed laser system used in high spectral resolution aerosol and cloud lidar applications. The PLC integrates a frequency doubling element, a waveguide splitter, and phase modulator into a monolithic, waveguide-based device. This technology is important for lidar systems r ...

AdvR, Inc. proposes the development of a highly efficient, fiber pigtailed, waveguide-based UV frequency converter module. This UV module will be an important element in future NASA sponsored Doppler lidar and High Spectral Resolution Lidar (HSRL) aerosol missions. The key innovation is the use of dual-element periodically poled waveguides embedded in a nonlinear optical substrate. This innovat ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

The global political structure has changed dramatically since the breakup of the former Soviet Union. World changes have caused the U.S. to reprioritize its National hypersonic needs. The United States government has looked to the needs of the future, and the hypersonic aeorospace plane is one of the systems included in alternative force structures. One of the hypersonic aerospace plane concepts w ...

S&K Electronics is proposing a visual programming environment for developing expert systems in CLIPS. This project will be known as the Visual Expert System Programming Resource, or VESPR. The visual environment will provide a graphical interface for easily capturing knowledge and converting it into the appropriate language constructs; it will also provide visualization of the system being develop ...

Nonlinear optical (NLO) materials play a critical role in current solid-state laser systems enabling broad tunability and operation at wavelengths not accessible by available laser gain media. At the same time, NLO materials limit the longevity and efficiency of these laser systems due to low damage thresholds, poor optical quality and small nonlinearities. As a result, new NLO materials are requi ...

NASA has a critical need to automate the identification and classification of features in Earth Science imagery, particularly new high-resolution imagery. In addition, commercial applications of Earth Science data as well as the viability of the remote sensing industry depend on the development of new tools for accelerated classification of remotely sensed images. Previous research by others to au ...

At the heart of scientific computing and numerical analysis are linear algebra solvers. In scientific computing, the focus is on the partial differential equations (PDEs) that arise from computational fluid dynamics (CFD), climate modeling, astrophysics, and structural and heat analysis that cannot be solved analytically. Certain problem formulations lead to sparse matrices, in which the majority ...

In this NASA SBIR Phase II effort, AdvR will design and build an efficient, fully integrated, waveguide based, source of spectrally uncorrelated photon pairs that will enable accelerated research and development in the emerging field of quantum information science. The key innovation is the use of sub-micron periodically poled waveguides to produce counter propagating photon pairs using quasi-phas ...
