A new all-optical approach for driving multiple highly dense nanolaser arrays has been developed by researchers in Korea. The method could enable chip-based optical communication links that process and move data much faster than current electronic-based devices.
“The development of optical interconnects equipped with high-density nanolasers would improve information processing in the data centers that move information across the internet,” said research team leader Myung-Ki Kim from Korea University. “This could allow streaming of ultra-high-definition movies, enable larger-scale interactive online encounters and games, accelerate the expansion of the Internet of Things and provide the fast connectivity needed for big data analytics.”
In a paper published today (December 15) in Optica, Optica Publishing Group’s journal for high-impact research, the researchers demonstrate that densely integrated nanolaser arrays — in which the lasers are just 18 microns apart — can be fully driven and programmed with light from a single optical fiber.
