  • Andrea Bernardi Presents TFLN-Based Quantum Photonics Breakthrough at World  of Photonics Congress 2025
    Jun 28, 2025 Andrea Bernardi Presents TFLN-Based Quantum Photonics Breakthrough at World of Photonics Congress 2025
    Andrea Bernardi, R&D Intern at AFR Milan, presented a  significant breakthrough in thin-film lithium niobate (TFLN)-based quantum photonics at the CLEO Europe – EQEC forum, during the World of Photonics Congress 2025.

    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.

  • AFR Showcased Latest Innovations for Optical Networks at OFC’2025
    Apr 07, 2025 AFR Showcased Latest Innovations for Optical Networks at OFC’2025

    Advanced Fiber Resources (AFR) showcased its latest innovations at OFC’2025, held April 1-3 at the Moscone Center in San Francisco. AFR highlighted several new and enhanced components designed for high performance and reliability in demanding networks.


    TFLN Modulators and Chips

    AFR presented multiple Thin-Film Lithium Niobate (TFLN) modulator products, including the 96/130 GBaud CDM and the AM70, both of which have already achieved volume shipment. AFR also debuted its 400 Gbps/lane PAM-4 TFLN modulator chip.

    During the event, AFR was invited to join the panel discussion “Commercial Readiness of TFLN Photonics,” where industry leaders shared perspectives on the commercialization path for TFLN technology. Additionally, AFR delivered a presentation at the Optica Tech Talk titled “Recent Developments in TFLN for Coherent and IMDD Applications,” exploring TFLN’s role in optical interconnects, data transmission, and quantum computing.


    Fiber Array Units

    Vlink, AFR's subsidiary, showcased its signature Fiber Array Units (FAUs) at the event, including CPO/OCS fiber arrays and PIC coupling fiber arrays, widely used in 400G, 800G, and 1.6T high-speed/ultra-high-speed optical modules, CPO applications, coherent transmission, DCI applications, and WSS modules. Vlink's core strength lies in its advanced manufacturing and packaging technology for optical components, its expertise in designing high-speed optical interconnect solutions, and its capability to rapidly scale customized products from prototype to mass production. With highly automated production lines ensuring precision and efficiency, Vlink delivers exceptional product quality while meeting the demands of large-scale manufacturing.

    C++, L++, C+L VGA EDFA Modules

    Designed by B&A, AFR’s subsidiary, the VGA EDFA modules support up to 120 signal channels (C++ and L++) or 96+96 signal channels (C+L). All amplifiers offer a wide gain range, low noise figure, fast transient control, and configurable modes including variable gain, variable output power, and manual mode. Ideal for backbone networks, MAN/OTN, and DCI.

    2-Pump and 4-Pump Raman Amplifiers
