The explosive growth in mobile and telecommunication markets has pushed the semiconductor industry toward integration of digital, analog, and mixed-signal blocks into system-on-chip (SoC) solutions. Advanced silicon (Si) complementary metal oxide semiconductor (CMOS) technology has enabled this integration, but has also led to a rise in costs associated with design and processing.
The Direct On-Chip Digital Optical Synthesizer (DODOS) program seeks to create a technological revolution in optical frequency control analogous to the disruptive advances in microwave frequency control in the 1940s. That early development ushered in a new era for microwave technology, transformed modern warfare, and has since been enabling a multitude of Department of Defense (DoD) and civilian capabilities, including radar, navigation technologies, and satellite and terrestrial communications. Extending frequency control to the optical regime is anticipated to greatly extend the technology base for the next generation of warfighter and other capabilities.
The general-purpose computer has remained the dominant computing architecture for the last 50 years, driven largely by the relentless pace of Moore’s Law. As this trajectory shows signs of slowing, however, it has become increasingly more challenging to achieve performance gains from generalized hardware, setting the stage for a resurgence in specialized architectures. Today’s specialized, application-specific integrated circuits (ASICs) — hardware customized for a specific application — offer limited flexibility and are costly to design, fabricate, and program.
Next-generation intelligent systems supporting Department of Defense (DoD) applications like artificial intelligence, autonomous vehicles, shared spectrum communication, electronic warfare, and radar require processing efficiency that is orders of magnitude beyond what is available through current commercial electronics. Reaching the performance levels required by these DoD applications however will require developing highly complex system-on-chip (SoC) platforms that leverage the most advanced integrated circuit technologies.
Due to engineering limitations and cost constraints, the dynamics of the electronic industry are continually changing. Commercial companies increasingly recognize the need to differentiate their products through research in areas other than device scaling, such as new circuit architectures and computing algorithms.
