Emerging photonic solutions hold the promise to transform avionics capabilities. Photonically enabled sensors and sources based on high-performance EO modulators and photodiode detectors exhibit extraor-dinary bandwidth and tunability. Photonic phased arrays possess unique capabilities to perform real-time, analog correlations in the optical domain via simple coherent interference, i.e. imaging. TCA...
The development of a novel metamaterial enhanced photonic RF receiver is presented. The receiver consists of a D-ring structure designed on an electro-optic LiNbO3 substrate to achieve direct modulation of RF signal into optical sideband. The optimized D-ring design provides strong electric field confinement, thereby resulting in significant improvement in detection sensitivity. Theoretical modeling,...
The ever expanding requirements of modern electronic receivers on decreasing platform sizes will mandate the use of multifunctional systems in the near future. Herein, we present an architecture for such a receiver based on optical upconversion techniques. This technology has already been utilized to demonstrate a distributed passive millimeter-wave imaging array that operates in real time.
