The Missing Link.

TEGEMA B.V. (NL), the multidisciplinary system integrator, has developed a modular machine platform for the automated assembly of optical components, in particular of photonically integrated circuits (PICs). The system, which works with submicron precision, can grow from tasks in research and development of PICs up to their series production thanks to its intelligent architecture. It provides a breakthrough in cycle time, which is 10-times shorter than in current solutions on the market. Ultrafast and high-precision active alignment systems from PI are at the heart of this photonic assembly platform.

"The lack of such a solution has so far hampered the market for photonic components. In a way, with this platform we have now created the missing link between the front end and the back end – a real breakthrough for integrated photonic circuits," stresses Arno Thoer, Director Technology & Engineering at TEGEMA, the importance of the development.

Versatile Platform

TEGEMA's modular platform architecture is the basis for the machine; it makes it possible to connect hardware modules specific to the application at hand. For the test and packaging of PICs, the Machine Vision systems for rough positioning, an adhesive dispenser, a UV light source for curing of the adhesive, and a rotation platform are used to transport the individual elements and, later on, the finished components in the machine. And at the heart of the platform: The active alignment system.

Heart of the Platform

Hidden deep inside, the active alignment system from PI forms the heart of the platform. Motion and positioning mechanics and firmware routines from PI make an ultrafast alignment of the optical elements possible in the submicroscale. The tracking mode compensates for position changes of the optical elements induced by stresses occurring during the curing of the adhesive. This special mode is part of the algorithm for the gradient search.

While up until now, about five to twenty minutes where necessary for the test and packaging of PICs, the machine from TEGEMA provides a fully assembled component, including active alignment and fiber termination, in about 30 seconds. Positioning normally only requires fractions of a second.

Depending on the requirement of the actual application, different versions of the alignment systems from PI are used – even up to the F-712.HA2 double-sided alignment system.

Modularity Enables Growth and Low Cost of Ownership

The compact design and modularity is what makes the platform of TEGEMA special. With a space requirement of nearly one square meter, it takes up very little space – which reduces the overall cost when used in expensive cleanrooms.

The system can be configured for use in research and development environments, for example in start-up companies, and so makes a fast assembly of PICs with signal-carrying glass fibers / fiber arrays possible, at a relatively small investment cost. If the production volume increases, modules can be added to reconfigure the system. Therefore, the machine grows with the production requirements.

The cost of photonic components is dominated by assembly and packaging processes. This is a drag on adoption at a time when rapid global scaling of connectivity is required. Part one of the webinar covers the presentation of TEGEMA's new "Modular Machine Platform Enabling A Breakthrough In Photonics Assembly Speed."

Part two of the webinar puts us "Inside the solution: Intelligent Micro-Robotics for High Throughput Photonics Manufacturing Automation." It explains why the precise alignment of individual elements of photonic integrated circuits is so important for costs and yield.
