Title (EN) SPLIT CONTROL OF FRONT AND REAR DBR GRATING PORTIONS
(FR) COMMANDE SÉPARÉE DE PARTIES AVANT ET ARRIÈRE DE RÉSEAU À RÉFLECTEUR BRAGG RÉPARTI
Abstract:
(EN) A method is provided for controlling a DBR laser diode wherein front and rear DBR section heating elements are controlled such that the reflectivity of the rear grating portion of the DBR section is lower than the reflectivity of the front grating portion of the DBR section. In this manner, lasing mode selection is dominated by the front grating portion and the front DBR section heating element can be controlled for wavelength tuning. In addition, the rear DBR section heating element can be controlled to narrow the spectral bandwidth of the DBR reflection spectra. Additional embodiments are disclosed and claimed.
(FR) L'invention porte sur un procédé pour commander une diode laser à réflecteur Bragg réparti (DBR), des éléments chauffants de sections DBR avant et arrière étant commandés de telle sorte que la réflectivité de la partie de réseau arrière de la section DBR est inférieure à la réflectivité de la partie de réseau avant de la section DBR. De cette manière, une sélection de mode laser est dominée par la partie de réseau avant et l'élément chauffant de section DBR avant peut être commandé pour un accord en longueur d'onde. En outre, l'élément chauffant de section DBR arrière peut être commandé pour rétrécir la bande passante spectrale des spectres de réflexion DBR. D'autres modes de réalisation sont divulgués et revendiqués.
