Process and device for the wavelength tuning of an optoelectronic component arrangement The invention relates to a process and a device for the wavelength tuning of an optoelectronic component arrangement, said optoelectronic component arrangement consisting of at least two optoelectronic components, with the objective of cost minimization. According to the invention, the characteristic wavelength for each optoelectronic component is set by means of a resistor arrangement (RM) connected between a common voltage source/ current source (U0/I) and the heater (H) of the respective optoelectronic component, wavelength tuning being accomplished by changing the heating power by means of changing the total resistance of the resistor arrangement (RM). The solution according to the invention is aimed at the wavelength tuning of solid-state lasers, optical amplifiers, filters, wavelength multiplexers and waveguides.
L'invention concerne un procédé et un dispositif qui, avec une réduction du prix de revient, permettent d'accorder la longueur d'onde d'une structure de composants électroniques constituée d'au moins deux composants optoélectroniques. Selon l'invention, on accorde la longueur d'onde caractéristique de chaque composant optoélectronique au moyen d'une structure résistante (RM) connectée entre une source de tension/de courant commune (U0/I) et un dispositif de chauffage (H) associé auxdits composants. Pour accorder la longueur d'onde, on modifie la puissance du chauffage en modifiant la résistance totale de la structure résistante (RM). L'invention permet d'accorder la longueur d'onde des lasers à semi-conducteur, des amplificateurs optiques, des filtres, des multiplexeurs et des guides d'onde.
