Scientists build the smallest optical frequency comb to-date 2

Scientists have built a photonic integrated, compact, and portable soliton microcomb source. The device is less than 1 cm3 in size, and is driven by an on-chip indium phosphide laser consuming less than 1 Watt of electrical power. It can be used in LIDAR, data center interconnects, and even satellites. https://www.sciencedaily.com/releases/2019/02/190211131457.htm
