Scientists build the smallest optical frequency comb to-date

(Ecole Polytechnique Fédérale de Lausanne) Scientists from EPFL and the Russian Quantum Center 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. The study is published in Nature Communications.
