• 40 GHz TFLN IQ Modulator – Featuring electro-optic bandwidth > 25 GHz and high linearity, suitable for OFDM, QPSK, QAM formats, and FMCW LiDAR.
• C-Band and 1060 nm Phase Modulator – Combining high linearity, low drive voltage, and compact footprint, supporting modulation up to 10 GHz for ultra-fast high-power lasers and quantum applications.

Innovations from AFR Subsidiaries: B&A and Vlink

Alongside AFR Milan’s showcase, AFR subsidiaries B&A and Vlink highlighted significant advances:

• 4-Pump Raman Amplifier (B&A) – Extends support to C++ bands, delivering low noise figure, flat gain, and high reliability for backbone and coherent transmission networks.
• Single Channel Nano EDFA (B&A) – A compact, low-power amplifier providing up to 6 dBm output power, optimized for single-channel systems and data center interconnects (DCI).
• 2D FAU for WSS (Vlink) – An innovative nonlinear 2D fiber array unit that achieves precise waveguide matching and improved coupling efficiency, enhancing optical path stability in wavelength selective switching (WSS) systems.

In  his  presentation, titled “Ultrafast  Post-Selection  Free Time-Bin  Entanglement  on  a Thin Film Lithium Niobate Photonic Chip,” Bernardi introduced a fully packaged, chip-integrated receiver  for  time-bin   entanglement  certification  that   eliminates  the   need  for  temporal post-selection — a first-of-its-kind  implementation  using an integrated  photonic  platform. The   device   is   based   on   AFR’s   commercial-grade   TFLN   technology   and   demonstrates high-speed operation with switching  rates  up to 5 GHz,  low  driving voltage (Vπ as  low as 3.37 V), and compatibility with CMOS electronics.

This  work  underscores  the   potential  of  AFR’s  TFLN  platform  for   real-world  quantum applications, marking a key milestone toward scalable, high-speed quantum networks. AFR remains committed to advancing integrated photonics through innovation, industrial-grade fabrication, and strong collaboration with leading research institutions.

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.
