Phys.org  February 28, 2024 An ideal integrated microwave photonics (MWP) processing platform should have both an efficient and high-speed electro-optic modulation block to faithfully perform microwave–optic conversion at low power and a low-loss functional photonic network to implement various signal-processing tasks, and large-scale, low-cost manufacturability. An international team of researchers (Hong Kong, UK, China) demonstrated such an engine based on a 4-inch wafer-scale thin-film lithium niobate platform. It could perform multipurpose tasks with processing bandwidths of up to 67 GHz at CMOS-compatible voltages. They achieved ultrafast analogue computation. They demonstrated these functions to show three proof-of-concept applications: solving ordinary differential equations, […]
