This SBIR Phase I effort will establish the feasibility of fabricating advanced waveguide structures in potassium titanyl phosphate (KTP) capable of efficiently generating 25 to 40 mW of frequency converted light in the 395 to 480 nm. The key innovation in this effort is to utilize KTP waveguides in a single-pass frequency doubling device to efficiently produce the desired laser wavelengths and po ...

This NIST Phase II SBIR effort will two low noise single photon detectors using MgO doped LiNbO3 (LN) periodically poled waveguides and a 980nm (or similar appropriate wavelength) pump to up convert 1550nm photons to 600nm to allow for detection by photomultiplier tube (PMT). The key innovation is using low noise periodically poled waveguides with a long wavelength (1800nm) pump leading to higher ...

The previously conducted Phase I project had two goals: (1) to prototype and evaluate the feasibility of an intelligent computer-based task management application that would improve the ability of persons with cognitive disabilities to perform activities of daily living (ADL) and (2) to identify objectives for full development of a deployable system in a Phase II project. Intelligent multimedia ...

An existing low-cost FPGA-based processing platform will be demonstrated with fiber-coupling to single-photon detectors, to perform photon-arrival time stamping with

A stable, well characterized InGaAs materials growth and photodetector fabrication process will be used to fabricate matched photodiodes optimized for balanced homodyne detection. The 1-mm-diameter p-i-n photodetectors will be manufactured back-illuminated with a 5-micron absorber, allowing residual light to reflect off the front-side metal to make a double pass through the active layer. Ultra-hig ...

Voxtel has demonstrated efficient high-speed photon counting with thresholded linear-mode avalanche photodiode (APD) receivers using multi-gain-stage InGaAs/InAIAs APDs. In contrast to Geiger APDs, thresholded photon-counting linear APD receivers are thought not to suffer afterpulsing, and can support maximum count rates (MCR) up to 2 or 3 orders of magnitude faster than Geiger APDs. However, the ...

This project team is developing a prototype of software for a tablet computer to replace paper tests for teachers to assess the reading fluency of special education students in grade 5 and 6. The technology will provide: scoring and tracking assessments with a stop watch for appropriate timing of questions, upload of data generated from the assessment directly to a database, audio playback capabil ...

GoGames will be a tablet-based multiplayer role-play game for middle school social studies classrooms and will focus on topics in civics. GoGames is intended to enable more efficient and effective implementation of traditional civics interventions by replacing static paper content and training manuals with dynamic interactive content and key information for gameplay. Modules will include LawMaker, ...

The web-based game, Numbershire II, will include modules to support students with or at-risk for disabilities in learning 2nd grade level mathematics, as defined by Common Core State Standards, including fluency with place value ideas, foundations of multiplication, and procedural fluency with multi-digit operations. In the narrative-based game, each student will build and maintain an idyllic Rena ...

The project goal is to develop and test the feasibility of a self-management system, Goal Guider, consisting of a mobile application and companion web site that allows individuals with intellectual disabilities and autism to effectively manage self-defined goals for everyday living across various personal, educational, and vocational life domains. Users will be able to easily enter goals, work wit ...
