On May 15th, as reported by the official account of China Optics Valley, fiber-optic communication networks can be likened to vast highways, where the transmission of an immense volume of data necessitates the utilization of 'oversized trucks' in the form of ultra-broadband photonic chips. Recently, the National Information Optoelectronics Innovation Center has achieved a remarkable feat by independently developing an ultra-broadband photonic chip that has established a new benchmark in data transmission capacity, boasting an impressive bandwidth of 250 gigahertz. Zhang Hongguang, the manager of the Future Technology Department at the center, revealed that leveraging this cutting-edge chip technology, the center has successfully crafted the world's inaugural 170 gigahertz intensity modulator. This groundbreaking innovation has already been integrated into domestically manufactured optoelectronic measurement equipment. Looking ahead, this chip is poised to offer foundational support for the 6G 'space-air-ground integrated' communication network and holds immense potential for application in satellite-based communication, thereby fostering the advancement of domestically produced satellite communication equipment.
