Whitepaper - Automate Photonics Alignment
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 drift causing position changes. It also covers a range of mechanisms, gantry platforms, hexapod mechanisms, modular alignment systems, mechanical bearing stages, and ACS Motion Control and Drive Modules, designed to meet various requirements. Additionally, it briefly touches on alignment applications beyond SiPh such as found in free space optical communication and multi-lens alignment for precision optics.
