High Throughput DC Production Testing of Laser Diode Modules and VCSELs

High Throughput DC Production Testing of Laser Diode Modules and VCSELs

Laser diodes (LDs) and VCSELs (Vertical Cavity Surface Emitting Lasers) are the primary components used in optical communications, spectroscopy, and a host of other important applications. As the demand for these applications grows, so does the need for the basic components themselves. This demand requires greater emphasis on developing accurate, cost-effective production test strategies. This note details a few cost-effective DC test systems that provide the high throughput required in today’s production environments.■
