Pulse Testing Of Laser Diodes


Pulse Testing Of Laser Diodes by Paul Meyer of 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.
