Lawrence A. Johnson, ILX Lightwave Corp.

What does a simple $10 laser pointer have in common with a space-qualified optical transmitter link? In each case, the reliability of the semiconductor laser diode used is a key concern. The commercial success of a laser supplier thus rests largely on its ability to develop a robust manufacturing process that consistently produces reliable devices. This must be combined with the quantitative assurances that the company can provide to customers to prove the devices’ reliability. As a result, the past two decades have seen an evolution of reliability testing equipment to support the diverse...Read full article
