Advanced Fiber Resources (AFR) , a global leader in fiber optic components, successfully participated in Laser World of Photonics 2025, held in Munich, Germany. From industrial lasers to next-generation optical networks, AFR’s portfolio addresses the industry’s growing demand for higher power, efficiency, and bandwidth. Key exhibits include the Gain Fiber and Free-Space Pumping Isolator, 20 W Compact In-Line Isolator, 3 kW Laser Cavity Component, and Lithium Niobate modulators.
Gain Fiber and Free-Space Pumping Isolator
AFR’s Gain Fiber and Free-Space Pumping Isolator handles 150 W average power and 200 kW peak power while limiting M² degradation to < 10 %. Ideal for for high peak and high average power fiber lasers.
20 W Compact In-Line Isolator
With a typical insertion loss of 0.7 dB, a minimum isolation of 30 dB and a maximum peak power of 10 kW for ns pulses, it enables efficient optical signal management in a compact size.
3 kW Laser Cavity Component
AFR's 3 kW Laser Cavity Component integrates a high power (kW) laser combiner and a fiber bragg grating in a compact package that reduces fiber splicing, improves electro-optical efficiency, and increases reliability in high power, continuous-wavelength fiber laser systems.
AFR also showcased a range of lithium niobate modulators, including 1060 nm Phase Modulator, 70 GHz Intensity Modulator (AM70), 20/40 GHz Intensity Modulator, and a 10 Gbps Zero-Chirp Modulator.
1060 nm Phase Modulator
AFR’s 1060 nm phase modulator delivers high linearity, low drive voltage, and low insertion loss across a frequency range from DC to 10 GHz, making it ideal for phase shifting, laser beam combining, and ultra-fast, high-power lasers.
70 GHz Intensity Modulator (AM70)
AM70 is a single Mach-Zehnder modulator based on thin-film lithium niobate (TFLN) technology. It offers high bandwidth, low insertion loss, low Vπ, and excellent linearity, all in a compact package with a G3PO RF connector and DC pins. The AM70 is well-suited for both analog and digital signal transmission in applications such as radio-over-fiber (RoF), sensing, and instrumentation.
As part of the conference program, Andrea Bernardi, Internship R&D, AFR Milan, presented the talk "Ultrafast post-selection free time-bin entanglement on a thin film lithium niobate photonic chip", highlighting recent joint advancements by AFR and its partners in integrated quantum photonic devices based on thin-film lithium niobate technology.
