Air Bearing Technology Helps Maximize Photonics Alignment Throughput

A new generation of miniaturized air bearing stages along with advanced alignment algorithms introduced powers a novel, compact multi-axis fiber alignment system. Based on friction-free air bearings, linear motors and a high-performance motion controller and software, the system enables fast and precise automated alignment of fibers, waveguides and other optical components. This multi-axis nanopositioning stage offers continuous and smooth motion, with its closed-loop motion controller providing nanometer resolution and long-term stability, making it an excellent fit for coupling optical signals into modern silicon photonics devices etc.

Unlike conventional ball bearings or crossed-roller bearings, the air bearings employed in the compact multi-axis alignment system have no wearing parts and require no lubrication. Additionally, air bearings produce no particles, making them ideal for clean-room environments. The air bearing/linear motor approach offers an almost infinite lifespan, ensuring a 24/7 operation.

While precision motion mechanics such as the F-142 alignment system are essential for achieving high throughput and quality results in modern fiber and silicon photonics alignment processes, the control software and firmware-based alignment algorithms are equally important. Faster and more effective alignments lead to better alignment quality and higher throughput, resulting in more efficient production and testing.

6-Axis Alignment Systems

Photonics alignment applications that require a 6-DOF motion system, 6-axis air bearing alignment engine can be used. Additional 6-axis and 12-axis alignment systems systems based on hexapod parallel kinematics and ultra-fast piezo scanners are also available.
