YOEC at LASER World of Photonics China 2026

On March 18, 2026, LASER World of Photonics China opened grandly at the Shanghai New International Expo Centre. YOEC (Yangtze Optical Electronic Co., Ltd.) presented its comprehensive solutions in fiber laser and fiber sensing technologies, featuring three core specialty fiber product lines, single-frequency narrow-linewidth laser modules with testing solutions, and distributed acoustic sensing (DAS) modules. The exhibition fully demonstrated YOEC’s strong capabilities and innovation in laser and sensing technologies.

Core Product Portfolio: Pushing Technical Boundaries and Setting New Industry Standards
Specialty Optical Fibers
Polarization-Maintaining Ytterbium-Doped Fiber: With high polarization extinction ratio (>30 dB) and low nonlinear effects, enabling performance improvements in high-power lasers and coherent communication systems.

Hollow-Core Anti-Resonant Fiber: Featuring ultra-low transmission latency (50% lower than solid-core fibers) and broadband transparency, providing disruptive solutions for 6G communications and high-power laser delivery.

Ring-Core Fiber: Offering uniform mode field distribution and high damage threshold, optimizing laser coupling efficiency for applications in precision processing and medical devices.

Single-Frequency Narrow-Linewidth Laser Modules & Testing Solutions
Designed for applications such as distributed fiber sensing and hydrophone systems requiring highly stable light sources, YOEC introduced single-frequency laser modules with linewidth <3 kHz, combining excellent optical performance with long-term reliability.

Key features include:

Low Noise & Ultra-Long Coherence Length: Low phase noise and relative intensity noise ensure high spectral purity, ideal for fiber optic hydrophones, high-resolution distributed sensing, and atomic physics experiments.

Highly Integrated & Lightweight Design: Modular architecture with standard 14-pin butterfly and compact Nano packages, suitable for space- and power-constrained platforms such as buoys, airborne, and naval systems.

Precision Closed-Loop Control & High Reliability: Integrated TEC and frequency stabilization technology, low power consumption, and MTBF exceeding 100,000 hours for demanding industrial and field environments.

Supporting Testing Solution:
YOEC also introduced a dedicated frequency noise measurement system for narrow-linewidth lasers, validated against mainstream products, enabling a complete technical loop for system development and performance verification.

Distributed Acoustic Sensing (DAS) Module
YOEC’s self-developed DAS module uses standard single-mode fiber as the sensing medium, enabling distributed detection of acoustic and vibration signals via optical scattering principles. It simplifies system integration while maintaining high performance.

The module integrates core optical components including ultra-narrow linewidth lasers (<2 kHz), acousto-optic modulators and drivers, erbium-doped fiber amplifiers, and polarization diversity units. Key advantages include high integration, ultra-high sensitivity, fully domestic core architecture, industrial-grade reliability, and precise localization and identification capabilities. It is widely applicable in oil & gas pipelines, perimeter security, rail transit, and utility tunnels.

Technical Exchange: Exploring Future Trends
On March 17, ahead of the exhibition, Dr. Lian Zhenggang, Technical Director of YOEC, was invited to speak at the 5th China Laser Leaders Conference. His keynote titled “Laser ‘Core’ Power: Specialty Fiber Supporting Technologies and Services” highlighted breakthroughs in large-core homogenized fibers and hollow-core microstructured fibers, as well as supporting technologies such as beam quality measurement and precision grating inscription.

He emphasized YOEC’s strategic positioning based on its specialty fiber expertise, addressing industry challenges and trends while delivering full-chain solutions for the laser industry. The presentation sparked active discussions among industry experts.

Exhibition Highlights: Strong Engagement and Collaboration Opportunities
During the exhibition, YOEC’s booth (Hall N5, Booth 5602) became a focal point for industry professionals. Live demonstrations of the single-frequency narrow-linewidth laser modules, frequency noise analyzers, and DAS modules received strong recognition from visitors. The technical team provided in-depth explanations, while the sales team engaged with customers, earning widespread praise for their professional service.

As an innovation-driven leader in specialty optical fiber technology, YOEC continues to push boundaries and empower the industry. At LASER World of Photonics China 2026, YOEC not only showcased its advanced product portfolio but also strengthened technical exchange and ecosystem collaboration, injecting new momentum into the global optoelectronics industry.

Looking ahead, YOEC will continue to advance in fiber-based energy and sensing technologies, working with partners worldwide to shape the future of intelligent sensing.
