ABSTRACT:
A method and device for tuning the wavelength of an optoelectronic component arrangement including at least two optoelectronic components. The characteristic wavelength for each optoelectronic component is adjusted using a respective resistance device which is connected between a common voltage/power source and a respective heating device associated with each optoelectronic component. Heating capacity is modified by changing the overall resistance of the respective resistance device (RM) in order to adjust wavelength. The wavelength of semiconductor lasers, filters, wavelength multiplexers and waveguides may be tuned.
