Formfactor helps manufacturers validate silicon photonics designs

Quantum ZeitgeistAugust 12, 20265 min read

As silicon photonics advances toward 1.6T optical interconnects, manufacturers face testing bottlenecks verifying photonic integrated circuit performance.

As data rates climb beyond 800G, silicon photonics is emerging as a key technology for efficiently moving massive amounts of data, yet verifying the performance of these complex devices presents significant hurdles. Manufacturers are now focused on wafer-level testing, combining traditional semiconductor probing with precision optical alignment to validate designs before packaging. FormFactor demonstrated how automated optical alignment improved silicon photonics testing efficiency through its collaboration with IHP, addressing a critical need as the industry looks toward 1.6T optical interconnects. This testing is a crucial step in moving these increasingly complex…
