Original Description Below.

DARPA is soliciting innovative research and development (R&D) proposals in the area of Silicon-based Photonic Analog Signal Processing Engines with Reconfigurability (Si-PhASER). The overall goal is the creation of novel silicon Photonic Integrated Circuit (PIC) elements and associated programmable filter array concepts, which can be fabricated in a CMOS-compatible process, and that enable high-throughput, low-power signal processors which overcome the limits of conventional electronic DSP technology. All administrative correspondence and questions on this solicitation, including requests for information on how to submit a proposal abstract or full proposal to this BAA, should be directed to [email protected]. See full BAA attached.
