Generation of quantum light deterministically and at telecommunications wavelengths has been an insurmountable challenge for execution of quantum networking protocols in a scalable manner, as telecom photons can travel with minimal loss through optical fiber networks, distributing quantum entanglement over long distances. Semiconductor quantumnbsp;dots have emerged as the most promising platform t ...

We are proposing the fully autonomous science facility REALISE for suspended biological cultures that can both incubate organisms over long periods of time (30 days to 9 months) but also perform in-situ analysis of samples using bright-field and three-color fluorescence microscopy. REALISE will be based heavily on functionality, components, and experience from past Shuttle, ISS, and Orion heritage ...

Photonectrsquo;s novel technology described in this proposal permanently attaches an optical fiber to a silicon chip using fusion splicing with methods and components that are scalable to high volume manufacturing, tolerant to mechanical and thermal stress, and limit loss. NASA has conveyed their need for coupling approaches and components resulting in low misalignment tolerances, which is directl ...

Incomplete, noisy, or otherwise uncertain data is the way it is, no purely computational method can magically fix it. Numerous techniques developed by the database and programming languages communities exist to help users cope with uncertain data. Specifically, these tools allow users to define business logic over uncertain (i.e., incomplete, possibilistic, or probabilistic) data as if it were ide ...

Rocket propulsion system development is enabled by rigorous ground testing to mitigate the propulsion system risks inherent in spaceflight. Helium is used in piping and engine purge processes to inert liquid hydrogen systems. The cost of helium is increasing as the supply diminishes, impacting testing of the rocket engines for space propulsion systems. There is an outstanding need within NASA prop ...

Vescent Photonics, LLC (Vescent) in collaboration with the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL) proposes to develop a compact ultra-narrow linewidth laser based on photonic integrated chip (PIC) technology for next-generation fieldable quantum sensor applications including optical atomic clocks, two-way time transfer, and precision inertial force and gravity sensing.nb ...

The proposed project aims to use ultrafast laser inscription (ULI) technology to improve the fabrication flexibility and versatility of a critical photonic component, arrayed waveguide grating (AWGs). The fabricated AWGs can be directly integrated with other ULI-based photonics devices, such as waveguide lasers, photonic lanterns, and modulators, realizing monolithic transmitters. This direct on-c ...

NASA is interested in improving the method to control CO2 and water in the Exploration Extravehicular Mobility Unit (xEMU) to meet the ambitious objectives of the Artemis program, which includes human presence on the surface of the Moon and Mars. The technology that is planned to be used is the RCA which utilizes two beds that are alternately used to remove CO2 and H2O and then are regenerated by ...

Circle Optics proposes a NASA SBIR Phase II project to build, flight test, and deliver, a 7-channel visible DAA visor system. This system would use Sony IMX530 sensors and provide staring type imaging over a plusmn; 112-degree horizontal FOV, with a plusmn; 15-degree vertical FOV, to support a detection range of ~ 3.8 Nm. At the beginning of the Phase II project, Circle Optics would confer with th ...

The Event-Based Sensing and Navigation Technologies (EBSNT) project aims to develop, integrate, and test a perception and planning avionics suite and associated on-board software in response to NASArsquo;s Subtopic ldquo;H6.22 Deep Neural Net and Neuromorphic Processors for In-Space Autonomy and Cognitionrdquo; within the scope of ldquo;Neuromorphic Software for Cognition and Learning for Space Mi ...
