LIV – High-power Laser Diode Testing
-
An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.
