The present invention relates to a method and device for reducing the phase noise of a laser signal from a laser source. This device comprises a first current generator for supplying a driving current to the laser source in view of producing the laser signal. A phase noise detector is responsive to the laser wavelength for generating a phase error signal and a second current generator is responsive to the phase error signal for generating a compensation current added to the driving current supplied to the laser source for generating a phase- adjusted laser signal. The device therefore defines a phase stabilization loop formed by the phase noise detector and the second current generator, for reducing the phase noise of the laser signal.

L'invention concerne un procédé et un dispositif permettant de réduire le bruit de phase d'un signal laser provenant d'une source laser. Ce dispositif comprend une première génératrice de courant destinée à alimenter un courant d'entraînement dans la source laser, afin de produire le signal laser. Un détecteur de bruit de phase répond à la longueur d'onde du laser, aux fins de génération d'un signal d'erreur de phase et une seconde génératrice de courant répond au signal d'erreur de phase, afin de produire un courant de compensation ajouté au courant d'entraînement fourni dans la source laser, aux fins de génération d'un signal laser à phase réglée. Le dispositif définit, par conséquent, une boucle de stabilisation de phase formée par le détecteur de bruit de phase et la seconde génératrice de courant, aux fins de réduction du bruit de phase du signal laser.
