NSF Award EAGER

The Optical Communications and Photonic Integration Group (OCPI) has been awarded a National Science Foundation grant to conduct exploratory research of light-based photonic molecule circuits and their applications.

NSF Award Search: Award#1745612 – EAGER: Large Scale Photonic Molecules and Applications. Additional award information can be found here.

The proposed exploratory research is aimed at realizing devices and functions with photonic molecules, the optical equivalent of electronic molecules. Research in photonics molecules seeks to use optically coupled photonic resonant microstructures to implement functions and behaviors with photons that are analogous to electronic atomic and molecular systems. Optical resonators can be thought of as photonic atoms and collections of photonic resonators can be designed to act like photonic molecules, enabling wide classes of new functions, systems and applications. The research outcome is expected to transform the field of photonic molecule technology by enabling new device functions that can be implemented using large-scale optical resonator arrays compatible with wafer-scale foundry integration. The ability to engineer molecular behavior based on photons has the potential to impact a wide variety of applications and revolutionize the performance, power, size and scaling of circuits difficult to realize with traditional electronics.

The proposed work combines photonic molecule techniques with a silicon nitride based integrated low-loss optical waveguide technology to demonstrate two transformative functions, a non-magnetic optical isolator and a fast acquisition high quality factor photonic circuit for real-time low-jitter frequency and phase recovery. These functions have proved to be difficult to realize with current integrated photonic technologies. Optical isolators and real-time frequency and phase recovery are both device functions that will impact the development of integrated optical digital and analog circuits and a wide variety of applications. New device simulation and design tools, layout tools, fabrication methods and testing methodologies will be developed. Broader impact of the proposed technology is the potential to decrease size, weight, cost and power of high-speed data communications technologies, special purpose hardware simulations of complex problems out of reach of today’s computers include many body physics, economic and transportation modeling, and medical solutions for biological sampling and disease detection.
