A laser driver system is disclosed that includes a first monitor current output node, a power set node, and a first feedback path. The first monitor current output node provides a first monitor current output signal that is representative of one of a bias current and a modulation current of the laser driver system. The power set node receives a power ratio set signal that represents a desired relationship of a power required for the laser driver to produce a high power level threshold to a power required for the laser driver to produce a low power level threshold. The first feedback path extends from the first monitor current output node to the power set node, and may be used for adjusting the power set signal when the monitor current output signal becomes non-linear.
