• The post references a paper on a broadband suspended lithium tantalate Mach–Zehnder modulator.
• The device achieves a 460 Gbit/s net data rate and uses a suspended thin-film lithium tantalate structure fabricated via silicon-substrate undercut.
• The figure shows the chip layout, fabrication flow, and a frequency response curve extending to roughly 110 GHz, underscoring the high-speed optical hardware angle.
