English Worldwide Technologies & Applications Solutions & Platforms News & Events Company & Corporate LIV – High-power Laser Diode Testing Testing and characterizing the light-generating devices at the very heart of photonics technology 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. To test if all functional components are meeting specifications, ficonTEC provides automated testing systems. The characteristic laser parameters are measured by running an LIV or, instead, a DC sweep. Parallel to the optical power, the optical output spectrum and near and far-field optical characteristics (amongst others) can also be measured. The latest integrated designs, which incorporate both electronic and photonic devices on a hybrid device, provide benefit in terms of functionality, miniaturization, high-volume manufacture and cost/part. However, these high-volume manufactured devices also present a number of challenges during device testing, and require ever higher levels of automation as well as highly parallel, mixed-signal electro-optical testing concepts, both on and off-wafer – a goal to which ficonTEC is already working toward. The accumulated data is written to an SQL Database, providing the user with the necessary statistical analysis and feedback so that e.g. yield can be tracked and improved. The system allows full component tracking and sorting when equipped with a handling system.
