Precision Automation Principles for the Optimal Testing and Packaging of PIC Devices

Photonics Spectra PIC No Text

About the Webinar

Production-scale testing of silicon photonic devices continues to be a challenge due to the multi-degree-of freedom, high-precision optical alignments required for wafer- and die-level testing. Wide variances in chip designs and coupling features complicate test procedures, making it difficult to identify a system capable of producing repeatable measurements across various topologies. Heintz provides a guide for selecting precision motion equipment to minimize the impact of positioning errors on optical alignment test results.


First, he introduces terminology typically used in the precision automation industry and the terms’ relationships to optical alignments. Next, Heintz discusses the fundamental principles of motion control and their impact on alignment quality. Finally, he presents a case study on error motions induced by 6-degree-of-freedom positioning devices and their impact on optical alignments to illustrate the importance of selecting the optimal positioning equipment for a given alignment application.
