White Paper on Improving Performance in Photonics Alignment: When Time is Money
Summary
The algorithms can be used with a wide range of hardware and applications, including mechanical motion stages, hexapod 6-DOF motion systems, fast piezo scanning stages, gantries for large area photonics test and validation, and even fast steering mirrors for free space optical communication. The whitepaper explores the expansion of photonics applications and the challenges faced in scaling up SiPh production, comparing precision requirements of photonics wafer probers with traditional wafer probers. It delves into the active alignment techniques necessary for precise positioning of signal-carrying elements, automation, advanced algorithms, and fast mechanics. The paper discusses different active alignment processes, including area scans, gradient searches, and compensating for position changes. We offer different solutions to exactly match the application, including low-inertia 6-DOF microrobots, modular direct-drive alignment systems with precision mechanical bearings, granite-based gantries for large area photonics test and assembly, and air-bearing-based multi-axis solutions free from friction, wear, and maintenance.
