This NASA Phase I STTR effort will establish the feasibility of developing a compact broadband near to mid-IR programmable optical comb for use in laser based remote sensing and communications. The comb generator will use a waveguide-based optical parametric gain block technology that can have ultra wideband (>250nm) operation with very high gain (>25dB) in a very compact footprint. This approach ...

To provide reliably secure communications, development of quantum optical devices for encrypted ground-to-space communications is a necessity. The overall goal of this NASA effort is to develop and deliver efficient, single-pass quantum optical waveguide sources capable of backward quasi-phase-matched interactions for generation of high purity photon pairs for use in an on-demand photon source to ...

This SBIR Phase I effort proposes to establish the feasibility of developing a UV Planar Lightwave Circuit (PLC); a compact, highly efficient, waveguide-based frequency conversion module for the generation of phase modulated UV radiation for use in multi-wavelength lidar applications such as NASA LaRC's HSRL program. The proposed module will provide phase modulated 355 nm radiation for calibratio ...

This Small Business Innovation Research Phase I effort will investigate the feasibility of using electro-optic (EO) beam scanning element to control coupling into a fiber as a fiber coupled pulse shaper. The goal of the pulse shaper is to reduce a 4-6ns pulse to 0.4-0.6ns pulse at 1064nm and/or 532nm at input powers at the 2mJ level. The highest utility of the proposed pulse shaper is its progr ...

There currently exists no end-to-end reactor/power conversion monitoring system that can provide both autonomous health monitoring, but also in-situ sensor calibration and response time testing without human interface. One of the key challenges facing space nuclear power systems is their extremely remote location and requirement for multi-year missions. The current benchmark system has a mission ...

The health and integrity of aircraft sensors and instruments play a critical role in aviation safety. However, inaccurate or false readings from these same sensors/instruments can lead to improper decision-making resulting in serious if not fatal consequences. This proposal offers a research and development (R&D) effort to demonstrate the feasibility of using advanced data analysis techniques to ...

The Universal Combustion Device Stability (UCDS) Process is the culmination of more than 40 years of research and provides the means to understand the complex dynamics and processes inside any chemical propulsion system, including liquid rockets, solid rockets, hybrid rockets, turbojet combustors and augmentors, and even scramjets. In addition to predicting whether a combustion chamber will oscil ...

The objective of the proposed work (Phases I and II) is to develop uncertainty quantification methodologies and software suitable for use in CFD simulations of aerodynamic flows, ranging from sub-sonic to hypersonic. We will address both pressure and density-based methods, as well as the class of algorithms addressing all-Mach number flows. The software developed here will be based on an existing ...

The overall objective of this proposal (Phases I and II) is to develop a robust and accurate solver for fluid-structure interaction computations capable of addressing multi-body flexible structures as well as rigid body motion. The fluid flow solution will be performed using our unstructured solution-adaptive flow solver TETHYS. We propose to develop a structural solver based on the Galerkin finit ...

The proposed "Observation platform for dynamic biomedical and biotechnology experiments using the ISS Light Microscopy Module" consists of a platen sized to fit the stage of NASA's Light Microscopy Module (LMM) on the International Space Station (ISS). At the heart of the innovation is a small hollow microscope slide into which specimens and reagent solutions can be injected by a combination of s ...
