Laser Diodes are current driven devices whose response (mA of current input to produce a mW of light output) can change significantly with temperature, age, and other effects. In this case, the diode is used in reverse mode so when no light is present, there. Perhaps the most important characteristic of a laser diode to be measured is the amount of light it emits as current is injected into the device. This generates the Output Light vs. Input Current curve, more commonly referred to as the L. The example when 30mA is injected to LD on graph1 is as follows.
