The inherent goodness of miniaturizing electronics has been key to a wide array of technology innovations and an important economic driver for several decades. For example, the seemingly endless shrinking of the transistor has allowed the semiconductor industry to place ever more devices on the same amount of silicon. Each time the size shrunk, transistors became faster and used less power, allowing increasingly capable electronics in smaller packages that cost less. In recent years, power requirements, excessive heat and other problems associated with physical limitations have reduced the advantages of continuing to shrink size.

DARPA-funded researchers have developed one of the world’s largest and most complex computer chips ever produced—one whose architecture is inspired by the neuronal structure of the brain and requires only a fraction of the electrical power of conventional chips.

DARPA’s Electronic-Photonic Heterogeneous Integration (E-PHI) program has successfully integrated billions of light-emitting dots on silicon to create an efficient silicon-based laser. The breakthrough, achieved by researchers working on the program at the University of California, Santa Barbara (UCSB), will enable the production of inexpensive and robust microsystems that exceed the performance capabilities of current technologies.

Whether designed to predict the spread of an epidemic, understand the potential impacts of climate change, or model the acoustical signature of a newly designed ship hull, computer simulations are an essential tool of scientific discovery. By using mathematical models that capture the complex physical phenomena of the real world, scientists and engineers can validate theories and explore system dynamics that are too costly to test experimentally and too complicated to analyze theoretically.

The manufacturing process for defense systems—from aircraft to vehicles to ships—is extremely complex and fragmented, often demanding unique materials and processes, complex certification requirements and specifications, and specialized tools and equipment. The almost inevitable result: lengthy production timelines and high costs. The manufacture of diverse small parts for military systems could be made simpler, faster, and less expensive with the development of a tailorable composite feedstock material and a single tailorable forming method.
