ficonTEC Service and Coherent Solutions to collaborate on ground-breaking measurement systems for photonics assembly and test

ficonTEC Service GmbH of Achim, Germany, and Coherent Solutions Ltd. of Auckland, New Zealand, have entered into a collaborative partnership to advance electro-optical measurement capability for use in volume testing within the manufacturing cycle of integrated photonic devices (PICs).

As optical and electrical technologies become more miniaturized, complex, and increasingly integrated with one another’s underlying architecture, the more inefficient and frustrating it is for process engineers to implement separate electrical and optical test and qualification procedures. To avoid this, engineers require fully-automated systems that can perform complex precision alignment and assembly, as well as combined electro-optical I/O measurements for complex integrated photonic devices – from singulated dies, through to wafer-level and even up to fully-packaged devices.

According to Ignazio Piacentini, Business Development Director at ficonTEC, “Wafer-level testing of PICs differs substantially from that of conventional semiconductor wafers and requires the integration of three major ingredients: Firstly, high-accuracy, sub–µm optical positioning with fast-active alignment capabilities. Secondly, some form of combined electro-optical probe head, and thirdly, modular high-channel-count instrumentation. ficonTEC and Coherent Solutions already provide the necessary capabilities for the first and last ingredients, and together we are actively researching electrical/optical probe head concepts.”

Coherent Solutions’ broad portfolio of photonic test and measurement instruments includes a line-up of modules for the popular PXI platform that leverage National Instruments’ established LabVIEW graphical programming environment. As ficonTEC’s PCM (ProcessControlMaster) software is also based around LabVIEW, integration of the two is seamless and enables the creation of sophisticated and fully-automated test solutions to match individual requirements.

Alternatively, to achieve the same goal within non-LabVIEW and alternative instrumentation environments, Coherent Solutions additionally offers the same optical measurement capability in a range of compact, modular benchtop and IOT-focused test equipment that can be equally well interfaced to ficonTEC’s process control software. Either approach can be flexibly used by manufacturers to speed up development and production of the latest photonic integrated circuits and devices.

Andy Stevens, CEO of Coherent Solutions says, “The last 20 years of investment into technology for optical communications is now spawning new capabilities and products in new applications and markets, which in turn encourages further development and innovation. We are fortunate to support this innovation and are incredibly excited to work with ficonTEC on new automated test and measurement solutions for manufacturers. Our complementary product platforms and design philosophies enable rapid customization and deployment and provide a clear upgrade path as technology advances and products evolve. For customers, this increases ROI and helps them bring new products to market faster and cheaper. Together, we will provide customers with unique products and unrivalled value and support.”

Torsten Vahrenkamp, CEO of ficonTEC Service added, “The collaboration with Coherent Solutions could not come at a better time, as a number of our current activities are geared to further improving performance and capability for our new, next-generation assembly and test systems. By integrating Coherent Solutions’ innovative optical instrumentation and software into our modular machine architecture and process control software, respectively, we take a significant step forward in our continued and growing support for integrated photonics developments worldwide.”

The two companies are initially focusing their sights on manufacturers of modules and components for telecom and datacom, and on systems for testing high-density VCSEL systems as used in 3D optical sensing/imaging applications, such as for automotive LIDAR and for face recognition modules found in smartphones.

ficonTEC and Coherent Solutions will display the initial results of this collaboration with a live demonstration of a fully-automated photonics test system at NIWeek in Austin, TX/USA, from May 20-23, and again at Laser World of Photonics in Munich, Germany, from June 24-27, 2019.
