Title (EN) LASER DEVICE AND METHOD FOR ITS OPERATION
(FR) DISPOSITIF LASER ET PROCÉDÉ POUR SON EXPLOITATION
Abstract:
(EN) A laser device has a photonic crystal surface emitting laser (PCSEL) element. At a first lateral side of the PCSEL element, a reflector is arranged to reflect back into the PCSEL element at least a portion of light travelling out of the PCSEL element through the first lateral side of the PCSEL element. Between the first lateral side of the PCSEL element and the reflector there is interposed an electrically controllable light-transmission region configured to control the transmission of light from the PCSEL element to the reflector, based on an electrical input. Also disclosed is a method of operation of a corresponding laser device.
(FR) L'invention concerne un dispositif laser doté d'un élément de laser à émission par la surface à cristal photonique (PCSEL). Au niveau d'une première face latérale de l'élément de PCSEL, un réflecteur est disposé pour réfléchir dans l'élément de PCSEL au moins une partie d'une lumière se propageant hors de l'élément de PCSEL à travers la première face latérale de l'élément de PCSEL. Entre la première face latérale de l'élément de PCSEL et le réflecteur se trouve interposé une région de transmission de lumière commandable électriquement configurée pour commander la transmission de lumière de l'élément de PCSEL au réflecteur, sur la base d'une entrée électrique. L'invention concerne également un procédé d'exploitation d'un dispositif laser correspondant.
