Active Alignment in Assembly and Connection Technology

Reliable manufacturing processes are essential for the assembly and interconnection technology of photonics and optoelectronics systems. One company, for example, uses active alignment during assembly—a method in which the actual maximum light coupling performance is achieved.

Fiber optic communication enables encrypted data transmission in civilian, industrial, and military environments. Lidar systems in autonomous vehicles capture their surroundings with the highest precision. Photonics is also an indispensable component for new applications in aerospace, medical technology, and quantum technology. Optical sensing, laser based distance measurement, and optical neural networks for AI driven systems require not only high technological standards but also reliable manufacturing processes.

A key role within these processes is played by active alignment technology. In contrast to passive alignment—where components are positioned according to geometric features—active alignment relies on signal feedback during assembly. This approach ensures not only geometric centering but also alignment to the actual maximum of light coupling. Such precision is especially critical in applications involving single mode fibers or silicon photonics systems, where even minimal deviations can lead to losses. Hybrid modules with multiple optical interfaces and non standard geometries also benefit from this alignment strategy. Tresky Automation combines nanometer level accuracy with flexible assembly methods across various coupling processes.

Tresky´s machine platforms cover the whole workflow—from component positioning and optical alignment to final bonding. Customer specific requirements as well as future scalability are taken into account. This results in manufacturing solutions suitable for research and development as well as for series production.
