Integrated Driver Circuit Figure 2 shows a solution with a dedicated APC laser driver IC 4 for CW operation up to 300 mA from a 2.4 to 15-V supply voltage. It requires only four additional passive ...

A wideband multiple resonance small-signal laser equivalent circuit model is presented to improve optoelectronic circuit design accuracy. Two important laser diode characteristics, such as input ...

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...
