The modulation bandwidth of silicon-based photonics is limited to approximately 60 GHz because of the maximum carrier mobility,which limits its development in high-capacity and high-speed information *** niobate has received much attention due to its excellent electro-optic properties.
We propose and experimentally demonstrate a batch dimension processing scheme based on the micro-ring weighting bank, which can at least quadruple the computing capability of the photonic tensor core without extra wei...
