5187_pulse_laser.pdfPulse Testing Of Laser Diodes By: Paul Meyer Keithley Instruments, Inc. Thermal management is critical during the testing of laser diodes at the semiconductor wafer, bar, and chip-on-carrier (submount) production stages. This has led to pulse testing of laser diodes to minimize power dissipation. Still, pulse mode testing requires careful selection and configuration of test equipment to avoid measurement errors and achieve the most cost-effective results. L-I-V Testing Basic Light intensity-Current-Voltage (L-I-V) testing is an I-V test with the addition of optical power measurements. This test is primarily used to sort laser diodes or weed out bad devices before they become part of an assembly. The device under test (DUT) is subjected to a current sweep while the forward voltage drop is recorded for each step in the sweep. Simultaneously, instrumentation is used to monitor the optical power output of the laser's front
