Scientists build the smallest optical frequency comb to-date
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.
Simons Foundation funds collaboration on stellarators
The Swiss Plasma Center participates in an international collaboration, funded by the Simons Foundation, to unveil the optimal magnetic configurations of stellarators so that their performances are similar to those of tokamaks - while retaining the advantage of being able to operate continuously. The optimization aims at exploiting the beneficial effect of some hidden symmetries that can be produced by specific arrangements of the magnetic coils.
