A Review of Electronic-Photonic Heterogeneous Integration at DARPA

The Defense Advanced Research Projects Agency (DARPA) has developed programs in integrated photonics for over a decade. From the Electronic-photonic Integrated Circuits (EPIC) program to the more recent Electronic-photonic Heterogeneous Integration (E-PHI) program, DARPA programs have established a library of high-performance silicon photonic devices and have demonstrated heterogeneous integration processes. These components and integration techniques, combined with automated design software tools, form the basis of the new American Institute for Manufacturing Integrated Photonics which will establish a photonics manufacturing ecosystem in the United States through a combination of public and private funds.
