    摘要: A method and a device is provided driving an optical laser diode (710, 711) during operation in an optical communication network, by
    - determining a laser transfer function (741, 742) during operation of the laser diode (710, 711) and
    - providing a control signal (750, 749) for driving the laser diode (710, 711) according to the laser transfer function (741, 742).
    The LD emission may be polarisation combined with the output of a second LD to provide non-polarized pumping light for a Raman optical amplifier used in an optical communication device. After the self-calibration of the two LD, during operation the calibration can be controlled by providing a modulation (770,771) on the LD bias current (778,779) and detecting (790,791) the voltage (716,718) over the LD (710,711). This information is used to update the L-I-slope as stored in the controller (740). Only a single monitor photodiode (730) is used for pump power stabilisation of the Raman amplifier as the control of the individual LD output power is performed via voltage and current measurements at the laser diodes.
