Neptec’s Photonic Leap: Advancing Silicon Photonics with Precision Fiber Arrays

At Neptec, we’re redefining the limits of silicon photonics infrastructure. Our next-generation fiber array units (FAUs) are engineered to meet the precision, density, and integration demands of tomorrow’s photonic chip systems, today. 

By bridging the gap between fiber optics and silicon photonics, we’re empowering researchers and hardware developers to scale architectures with unparalleled accuracy and efficiency.

Precision Fiber Array Units for High-Density Photonic Systems

Our custom precision FAUs are purpose-built for this challenge, offering industry-leading alignment and fiber density:

• 12, 16, 36, and 72-channel FAU with 80/127/250 μm pitch for reliable, high-throughput optical pluggable interconnects.

• Sub-micron alignment accuracy, critical for minimizing signal loss during transmission.

  
  

These custom FAUs are optimized for seamless packaging with photonic chips, supporting both edge coupling and grating coupling.

Wafer-Ready Validation and Reliability

Our commitment to faster and higher bandwidth performance doesn’t stop at design, we rigorously validate every FAU through extensive testing to ensure real-world robustness and fidelity:

• Insertion loss mapping for consistent channel performance.

• Polarization extinction ratio verification for entanglement-sensitive systems.

Enabling the Next Generation of Scalable Silicon Photonics Architecture

Neptec’s FAUs aren’t just components, they’re enablers of faster data transfer rates. Our technology directly addresses the key scalability and performance challenges facing the silicon photonics industry:

1. Density Scaling

   With 80/127μm pitch arrays, a single photonic chip can support hundreds of fiber interfaces, making large-scale silicon photonics systems more practical than ever.

2. Signal Integrity

   Our PM fiber solutions preserve polarization within +/- 3 °, slow and fast axis alignment, stress rod angular tolerance.
