GRACYFIBER's polarization-maintaining fiber array (PMFA) is a high-precision micro-optical interconnect component designed for stringent polarization control and high coupling stability. This product ensures extremely high polarization extinction ratio (PER) and excellent signal consistency across multiple channels by precisely aligning polarization-maintaining fibers in a V-groove substrate. Whether you are developing next-generation silicon photonics (SiPh) packages, co-packaged optics (CPO), lithium niobate (LiNbO₃) modulators, or coherent optical communication systems, we offer highly scalable customization options (supporting 1 to 128 channels). With flexible lidded or lidless structures, this component seamlessly integrates into edge-coupled and end-face coupling processes, directly helping optical module manufacturers reduce polarization-dependent losses and accelerate the mass production process of high-end chip-scale packaging.

Features: Extremely high polarization extinction ratio (PER ≥20 dB, typical ≥23 dB)
Benefit: Ensures extremely high polarization purity of optical signals in multi-channel transmission, effectively eliminating polarization crosstalk. This provides unparalleled signal integrity for your high-speed coherent optical modules and high-end optical sensing systems.
Features:High-precision polarization axis alignment (≤ ±2°, typical ±1°) and flexible axial control (0° / 45° / 90° or custom)
Benefit:Ensures perfect polarization axis matching between the array and the silicon photonics chip or LiNbO₃ modulator. This significantly reduces polarization dependent loss (PDL) during active alignment, improving overall optical coupling efficiency and system stability.
Features:Submicron-level fiber core pitch tolerance (±0.3 μm to ±1.0 μm) and ultra-high channel scalability (1 to 128 channels)
Benefit: Precisely supports standard pitches such as 127 μm and 250 μm. This not only meets the stringent space requirements from simple interconnects to complex CPO systems, but also helps your hardware architecture easily achieve high-density photonic integration and smooth upgrades.
Features:Ultra-low insertion loss (≤0.5 dB, typical 0.3 dB) and high return loss (APC ≥55 dB)
Benefit:Maximizes your system optical power budget, meeting the stringent optical power requirements of high-order coherent modulation formats, thereby effectively extending transmission distance and reducing network bit error rate.
