Abstract
A device for adjusting laser diodes includes a pilot signal adjustment device for adjusting the signal current using a pilot signal frequency that is modulated onto the signal current. The device includes a bias direct current source supplying the laser diode with a bias direct current. A switching device switches the adjustment device between a state where the pilot signal adjustment device is connected to the modulator and the bias direct current source such that the signal current can be adjusted using the pilot signal adjustment device, and another state where the modulator is connected to the temperature compensation device such that the signal flow can be adjusted and/or controlled by the temperature compensation device.
