Nous avons démontré la suppression active des sauts de mode dans des lasers à semi-conducteurs à cavité externe, incluant un réseau de diffraction comme dispositif de sélection de longueur d'onde. La commande par rétroaction annule la différence entre la longueur d'onde d'oscillation et la longueur d'onde sélectionnée sur la base des changements observés dans l'angle de diffraction. Le contrôle a supprimé les sauts de mode sur une plage 7.5 fois plus large que sans contrôle. Et lorsqu'elle est combinée avec des techniques conventionnelles de suppression de saut de mode, une oscillation sans saut de mode est obtenue sur 130 nm. Notre approche peut être utilisée pour la plupart des lasers à semi-conducteurs à cavité externe de type Littman avec des fixations simples ; il sera utile pour le balayage continu des longueurs d'onde et pour la stabilisation des longueurs d'onde à long terme.

Abstract: We have demonstrated active mode hopping suppression in external-cavity semiconductor lasers including a diffraction grating as a wavelength-selecting device. The feedback control nullifies the difference between the oscillation wavelength and selected wavelength based on observed changes in diffraction angle. The control has suppressed mode hopping over a 7.5 times wider span than without control. And when combined with conventional mode hopping suppression techniques, mode-hop-free oscillation is achieved over 130 nm. Our approach can be used for most Littman-type external-cavity semiconductor lasers with simple attachments; it will be useful for continuous wavelength sweeping and for long-term wavelength stabilization.
