Lightera's ErYb Optical Fiber: Revolutionizing High-Power LiDAR and Free-Space Communication

26 Aug 2025

Lightera’s (formerly OFS) Large Mode Area (LMA) Polarization Maintaining (PM) Erbium-Ytterbium (ErYb) optical fiber is designed to revolutionize high-power LiDAR and free-space communication applications, setting new benchmarks in performance and reliability.

Unmatched Performance and Reliability

Building on Lightera’s proven high-power gain fiber portfolio, including the industry-leading TrueLase™ Yb Premium Optical Fibers for 3kW+ output power, the ErYb fiber offers unparalleled performance. With a robust design that enables consistent delivery of over 100W average power at 1550 nm, this fiber ensures high TMI threshold and low photodarkening. The 25 µm core and 300 µm cladding architecture provide low non-linearities and exceptional beam quality, making it ideal for demanding applications.

Advanced Capabilities for Diverse Applications

This enhanced design minimizes higher-order mode (HOM) content, allowing for high output power suitable for applications such as ground-to-satellite communications and airborne LiDAR. Additionally, the highly manufacturable design and high-volume fabrication processes ensure consistent product quality without compromising performance.

Key Features and Applications
