Large-Scale High-Speed Photonic Switches Fabricated on Silicon-Based Photonic Platforms

Large-scale high-speed photonic switches were demonstrated on silicon-on-insulator and thin-film Lithium Niobate platforms, respectively. Ultra-low-loss spot-size-converter, grating coupler, waveguide crossing, and high-speed switch unit are developed, as well as an integrated 128 × 128 switch.
