Chip-based laser reportedly stayed locked without active electronic control
Phys.org reported in a social post that the device cut frequency noise by more than 5,000-fold across its tested drive-current range and linked the work to EPFL and Nature Photonics.
TLDR
A Phys.org social post says a chip-based laser stayed locked without active electronic control and reduced frequency noise by more than 5,000-fold across its tested drive-current range versus its free-running state. The post linked the work to EPFL and Nature Photonics, but the supplied evidence does not include the underlying paper or further methodological detail.
