Latest Patents

Tong Ge holds a patent for an "Integrated lithium niobate microwave photonic processing engine." This invention is based on a thin-film lithium niobate (LN) platform capable of performing computation tasks of analog signals at speeds of up to 92G samples per second. The integrated MWP processing engine combines a high-speed electro-optic modulation block with a multi-purpose low-loss signal processing section on the same chip, fabricated from a 4-inch wafer-scale process. This technology demonstrates high-speed analog computation, including first- and second-order temporal integration and differentiation, achieving computing accuracies of up to 98.1%. The patent showcases three proof-of-concept applications: ordinary differential equation solving, ultra-wideband signal generation, and high-speed edge detection of images. Furthermore, the image edge detector enables a photonic-assisted image segmentation model that effectively outlines the boundaries of melanoma lesions in medical images, achieving significantly faster processing speeds and lower power consumption compared to conventional electronic processors. The ultrafast LN MWP engine provides compact, low-power, low-latency, and cost-effective solutions.
