Not Available Silicon-based devices have remained the workhorse of the solid state device community. As the need for higher processor rates is ever increasing, silicon-based systems are being pushed to their limit. In addition, due to the indirect bandgap of silicon, light emission is not possible. We propose an entirely new approach to processor technology. In this project, we will construct ...

Not Available This Small Business Innovation Research Phase I project will investigate the technical feasibility of fabricating an affordable blue laser array for projection displays. Our concept uses a new approach to fabricating lithium-niobate-based quasi-phasematching frequency converters to efficiently frequency-double low-power commercial diode lasers t produce blue light. A novel device ...

Not Available In this project, Foster-Miller will evaluate the likely failure modes, and the sensor and electrical signals available in the systems controllers for performing diagnostics evaluations on advanced aircraft electric actuation systems. An overall concept will be developed for a prognostics system for the electrical control and actuation systems on a More Electric Aircraft. This concep ...

Not Available Photonics offers 'denser computing capability' because of the extraordinary large bandwidth that it offers. However, a common problem is splitting-loss whereby signal strength per channel is reduced whenever a signal is split. For an economic and compact solution to this problem, there is the need for multi-function devices that combine splitting and amplification of light. Erbium-d ...

We will investigate the feasibility of a signal processing system that controls the perceived location of a virtual sound source for listeners wearing headphones. Starting from an approximate head-related transfer function (HRTF) individualized HRTFs will be adaptively approximated for observers in a psychophysical task. Average HRTFs have proven inadequate for consistently placing sound sources ...

Not Available IFOS proposes to develop novel photonic signal-processing subsystems to replace certain electronic signal-processing functions presently limiting many sophisticated systems such as radar. Using photonics for signal processing and computing holds promise for ultra-high bandwidth and speed, immunity to electromagnetic interference and crosstalk, freedom from impedance-matching problem ...
