PINovAlign - Cost-Optimized, High-Speed Fiber-Alignment System for Silicon Photonics

Available in 3-asix to 6-axis variants for single- and dual-sided fiber and fiber-array applications.

SHREWSBURY, Mass., Nov. 11, 2025 /PRNewswire/ -- PI (Physik Instrumente) offers a new 6-axis variant of its successful F-141 PINovAlign automated fiber alignment system. The F-141 is a compact, cost-optimized high-performance alignment solution providing precision motion in 2, 3, 4 and degrees of freedom for the industrial test and assembly of photonic integrated circuits (PICs), fibers and fiber array units (FAU). Designed for space-limited environments, the F-141 fits within a footprint of just 5 x 7 x 4 inches (WxLxH) while delivering 40 mm of XYZ travel and ±12° of rotation—ideal for array alignment tasks.

Direct-Drive Design Provides for High Dynamics
Powered by direct-drive motors, the system achieves high acceleration, speed, and resolution with long lifetime and maintenance-free operation. Crossed-roller bearings and flexure guides ensure smooth, precise motion and repeatable performance.

Optional 6-Axis Version
In addition to 2-, 3-, and 4-axis models, the F-141 is available with an optional pitch/yaw module for fully automated six-degree-of-freedom alignment. Custom configurations are also available for different optical axis orientations.

Advanced Alignment Control and Integrated Intelligence
The F-141 is driven by PI's EtherCAT®-based multi-axis alignment controller, featuring rapid signal analysis and onboard machine learning. Embedded scan and alignment routines deliver faster and more reliable results than conventional host-based algorithms, simplifying system integration and boosting throughput.

Fastest First-Light Detection in the Industry
PI's proprietary alignment algorithms enable industry-leading first-light acquisition and signal optimization speeds—up to 100× faster than conventional techniques. Leveraging ultra-low-noise electronics, pulse-width modulation (PWM) amplifiers, and 24-bit analog-to-digital converters for high-bandwidth optical power monitoring, the F-141 delivers highly stable and repeatable optical coupling performance, even under challenging environmental conditions.

SPIE Prism Award Finalist 
The F-141 PINovAlign system was also recognized as a finalist for the SPIE Prism Award in the Test & Measurement category. The winners will be announced in January 2026, during the Photonics West Conference in San Francisco.
