High performance optoelectronic systems, e.g. ultra low-noise lasers and optoelectronic signal sources, are employed in numerous applications such as fiber optic communications, high-precision timing references, LADAR, imaging arrays, etc. Current state-of-the-art ultra-low noise lasers and optoelectronic signal sources use macro-scale photonics for mechanical and thermal noise suppression, and off-chip electronics for feedback control. The benchtop or rack mount component-level assembly of these sources limits photonic coupling efficiency as well as the speed of electronic feedback, and also adds size and weight to the system. Integration of these components in a chip-scale form factor could greatly mitigate these limitations.
The DAHI Foundry Technology program thrust seeks to establish an accessible, manufacturable technology for device-level heterogeneous integration of a wide array of materials and devices (including, for example, multiple electronics and MEMS technologies) with complex silicon-enabled (e.g. CMOS) architectures on a common silicon substrate. of The DAHI Foundry Technology thrust will incorporate and build upon the heterogeneous integration technologies of the COSMOS and E-PHI program thrusts, while also developing new capabilities in heterogeneous integration processes, yield and circuit design innovation. 
Modern networks and platforms rely on access to the radio frequency (RF) spectrum for communications, radar sensing, command and control, time transfer, and geo-location. Electromagnetic interference, due to congestion in the spectrum or malicious jamming, can have catastrophic effects. Countering such interference is particularly important for unmanned platforms. To address this challenge, the Hyper-wideband Enabled RF Messaging (HERMES) program seeks to provide an assured link for essential communications by developing a jammer- countering capability that is orders of magnitude beyond the state-of-the-art.
The increased density of components in today’s electronics has pushed heat generation and power dissipation to unprecedented levels. Current thermal management solutions, usually involving remote cooling, where heat must be conducted away from components before rejection to the air, are unable to limit the temperature rise of today’s complex electronic components without adding considerable weight and volume to electronic systems. The result is complex military systems that continue to grow in size and weight due to the inefficiencies of existing thermal management hardware.
The Mesodynamic Architectures (Meso) program seeks to address future Defense needs by exploiting unique characteristics of matter and energy emerging at small spatial and short temporal scales including new states of matter, untapped forces, novel relationships between fields and excitations and the importance of noise and nonlinearity. The parallel goals of the Meso program are to provide DoD with unrivaled communication, sensing, and computation by exploiting mesoscale characteristics, while establishing well-defined problems to accelerate the transition to quantum engineering.
