Introduction

In the rapidly evolving field of silicon photonics, the need for precise and efficient fiber alignment systems has never been more vital. Enter the F-141 PINovAlign, a state-of-the-art automated fiber alignment system developed by PI (Physik Instrumente). This advanced system presents a compact and cost-effective solution for aligning fibers in various applications, including integrated photonics testing and assembly. With its versatility and innovative features, the F-141 is poised to set a new standard in the industry.

Features of the F-141 PINovAlign

Compact Design

One of the most remarkable attributes of the F-141 is its compact design. Measured at only 5 x 7 x 4 inches (WxLxH), it can easily fit into tight spaces, making it ideal for environments where real estate is at a premium. Despite its small size, the system achieves 40 mm of XYZ travel and allows for ±12° of rotation, catering to a wide array of alignment tasks.

Advanced Motion Control

The F-141 features a direct-drive design optimized for high dynamics, powered by direct-drive motors that provide remarkable acceleration, speed, and resolution. This innovative motor configuration ensures longer operational lifetime and virtually maintenance-free performance. Additionally, crossed-roller bearings and flexure guides contribute to smooth and precise motion, resulting in repeatable performance crucial for high-precision applications.

Variants for Diverse Needs

Understanding that different alignment tasks may require specific configurations, the F-141 system offers models with 2, 3, 4, and 6 axes. The optional six-axis configuration includes a pitch/yaw module, enabling comprehensive six-degree-of-freedom alignment. This flexibility makes the F-141 suitable for both single-sided and dual-sided fiber and fiber-array operations.

Integrated Technologies

Intelligent Control System

At the heart of the F-141 PINovAlign lies its EtherCAT®-based multi-axis alignment controller, renowned for rapid signal analysis and integrated machine learning capabilities. The system is equipped with embedded scan and alignment routines that significantly enhance processing speeds compared to traditional host-based approaches. This integrated intelligence not only simplifies system integration but also boosts overall throughput, making it an invaluable tool for high-volume testing.

High-Speed First-Light Detection

One of the standout features of the F-141 is its proprietary alignment algorithms, which enable extraordinarily fast first-light acquisition and signal optimization—up to 100 times quicker than conventional methodologies. By harnessing ultra-low-noise electronics, PWM amplifiers, and 24-bit analog-to-digital converters, the system ensures stable and repeatable optical coupling performance even in challenging environmental conditions.

Recognition

The F-141 has garnered industry acclaim, securing a finalist spot for the prestigious SPIE Prism Award in the Test & Measurement category. Winners will be revealed in January 2026 during the Photonics West Conference in San Francisco, adding to the system's growing reputation in the field.

Applications and Industries

The F-141 PINovAlign system has been tailored for diverse applications, particularly in the fields of:

• - PIC Alignment: Ensuring precise alignment of photonic integrated circuits for optimal performance.
• - Fiber Alignment: Facilitating quick and accurate alignment of fiber optics for transmissions.
