In many photonic systems, the emitter is a laser source, whose noise becomes the main system limitation, even if it can be considered low. Many laboratories in the world study coherent sources to address different areas of applications : fundamental research (quantum,
gravitational waves...), defense, telecommunications, environment...
A research theme of the Foton Institute concerns coherent sources. We acquire an expertise in the realization of coherent sources. The latest works concern the study of Brillouin lasers at the best state of the art. Thus, we have realized very coherent C-band-tunable sources. We do not know how to characterize these sources in terms of coherence because they are below the noise floor of our characterization bench (sub-mHz intrinsic width and sub-kHz integrated noise). This work has revealed the physics of synchronization by an ultra-coherent laser. This type of source allows significant advances from a scientific and industrial point of view (fundamental study of synchronization processes, instrumentation, realization of sensors,...)
