China has unveiled the world's first 170-GHz thin-film lithium niobate electro-optic modulator, marking a breakthrough in the country's ultra-high-speed optical conversion technology.
As the “signal-conversion heart” of optical communication systems, the matchbox-sized core device not only fills a domestic gap in key components for high-end testing and measurement equipment, but also provides crucial hardware support for future 6G communications and next-generation information infrastructure.
