The POEM program aims to address electrical communications link limitations by developing chip-scale, integrated photonic technology to enable seamless intrachip and offchip photonic communications that provide the required bandwidth with low energy/bit. The POEM program will exploit wavelength division multiplexing (WDM), allowing much higher bandwidth capacity per link, which is imperative to meeting the communication needs of future microprocessors. Such a capability would propel the microprocessor onto a new performance trajectory and impact the actual runtime performance of DoD-relevant computing tasks for power-starved embedded applications and supercomputing.
The Precise Robust Inertial Guidance for Munitions (PRIGM) program is developing inertial sensor technologies to enable positioning, navigation, and timing (PNT) in GPS-denied environments. PRIGM comprises two focus areas: development of a navigation-grade inertial measurement unit (NGIMU) based on micro-electromechanical systems (MEMS) platforms, and basic research of advanced inertial micro sensor (AIMS) technologies for future gun-hard, high-bandwidth, high-dynamic-range, GPS-free navigation.
Defense applications, such as geo-location, navigation, communication, coherent imaging and radar, depend on the generation and transmission of stable, agile electromagnetic radiation. Improved radiation sources—for example, lower noise microwaves or higher flux x-rays—could enhance existing capabilities and enable entirely new technologies.
Real-time assessment of the electromagnetic environment can provide a key tactical advantage. The rapid development and proliferation of advanced radios, however, has made this a challenging task. Radio frequency (RF) sensor systems on the modern battlefield must cover many RF and microwave bands through noise and powerful interferers. Ultra-wideband analog-to-digital conversion (ADC) has emerged as an essential technology to interface between propagating analog RF signals and digital processing for reactive decision-making. Such an ADC allows for high-speed and reconfigurable digital processing in a complex electromagnetic environment.
Conventional optical imaging systems today largely limit themselves to the measurement of light intensity, providing two-dimensional renderings of three-dimensional scenes and ignoring significant amounts of additional information that may be carried by captured light.
