ABSTRACT:
A laser driver for an injection laser diode (ILD) protects the ILD during ILD temperature changes so that the ILD is not subjected to a potentially harmful operating current. The ILD may be operated near it maximum limit and modulated by decreasing the available current to the ILD. The temperature of the ILD may be sensed and the maximum ILD driving current changed proportionally to a change of the sensed temperature.
