Australian researchers create an internet connection with speeds reaching up to 44.2 terabits pers second, a record achieved over 75km of glass fibre using a single optical chip.
Hailing from Monash, Swinburne and RMIT universities, the researchers managed to create such a connection using a "micro-comb." According to the paper detailing the experiment, the micro-comb “generates very sharp and equidistant frequency lines in a tiny microphotonic chip.” In a few words, the micro-comb loops light around a ring to produce 80 beams at various infrared wavelengths. Each beam carries a stream of data, and since all the wavelengths of light are all correlated, the data streams could be "packed" tightly together using nearly all the available light spectrum.
