Abstract: A method for controlling tuning current values provided to a multichann el laser source. For each operating laser channel, a desired slope value of las er power as a function of tuning current is stored. The slope values of laser power as a function of tuning current is then measured. The tuning current is then adjusted until a slope value substantially close to said desired slope value is measured. The operating tuning current is set for the laser source that corresponds to the measured slope value.
