Fiber Array Units (FAU)
Micro-Optics for Precise Mode-Field Matching, Low-Loss Fiber-to-Chip Coupling, and High-Density FAU Architectures
Fiber Array Units (FAUs) are key components in modern optical data communication systems. They enable the precise alignment and parallel coupling of multiple optical fibers to photonic integrated circuits (PICs), laser modules, and optical engines. In data centers, HPC systems, and AI clusters with rapidly increasing bandwidth demands, FAUs are essential for scalable, energy-efficient, and reproducible optical coupling.
Optical Requirements for Fiber Array Units (FAUs)
Fiber Array Units (FAUs) integrate beam-shaping optics to precisely match the mode field, beam profile, and numerical aperture between the optical fiber and the target photonic structure. The optical design and manufacturing precision of these optics determine insertion loss, return loss, channel uniformity, and the long-term stability of the coupling, and place high demands on optical precision, alignment tolerances, and thermomechanical stability.
Custom Micro-Optics for FAUs
INGENERIC’s precision glass molding technology delivers optical components with exceptionally high reproducibility, making it a key enabler for demanding applications such as Fiber Array Units (FAUs). It provides FAU designers with new degrees of freedom in design, scalability, and manufacturing reliability. Our optical designs are developed application-specifically and tailored to your technical requirements, ensuring optimal alignment of optical performance, efficiency, and system integration.
Precision glass molding enables the reliable realization of complex fiber and optical geometries (125 µm / 250 µm) that are difficult to achieve with conventional manufacturing methods
High reproducibility of molded micro-optics minimizes geometric tolerances in FAUs, ensuring consistent optical performance across all channels
Homogeneous microlens arrays produced by precision glass molding support FAU architectures with significantly higher fiber counts than conventional 8, 12, or 16-channel designs—without compromising optical quality
High-precision micro-optics ensure well-defined mode-field matching between fiber and target structure, reducing insertion loss and channel-to-channel variations
