In this Project, OEwaves Inc. and Georgia Tech team propose to research and develop a unique RF photonic receiver front-end enabling microwave signal processing at a heterogeneously integrated photonic platform. In particular, we propose to develop a new technology for photonic microwave filters based on the new advances in Si-based integrated photonics. We will exploit the expertise of the team members who have made extensive contributions to silicon (Si) and silicon nitride (SiN) integrated photonic structures (Georgia Tech) and the design and development of analog photonic systems (OEwaves Inc.).
These photonic integrated circuits permit size, weight, power and cost reductions for spacecraft microprocessors, communication buses, processor buses, advanced data processing, free space communications and integrated optic science instrument optical systems, subsystems and components. Allowing NASA to respond to the steady increase in data rates, with signal coding and modulation for more efficient use of the RF spectrum establishing reliable radio links across thousands of miles of space.
Various military airborne intelligence, surveillance, and reconnaissance (ISR) as well as government software defined and cognitive radio applications had demonstrated great need for such a tunable microwave-photonic filter. Customers include the federal government (DoD, NSA, etc.), government/defense contractors (Lockheed Martin, BAE Systems, L-3, Northrop Grumman, UTC Aerospace, etc.), and government communication radio developers (Motorola Solutions, Harris, National Instruments, etc.).
