Chinese researchers invent silicon photonic multiplexer chip that uses light instead of electricity for communication — CCP says China's early steps into light-based chips precede 'major breakth

Fudan University researchers have allegedly developed a photonics-based multiplexer chip, supporting up to 38 Tbps data transmission. While not yet a full CPU, Chinese industry observers believe China's big breakthrough in photonics will arrive in "three to five years".
