Fiber Alignment Arrays Fabrication

We offer optical fiber alignment arrays (1D, 2D micro-hole arrays) fabrication services.

Our solution enables reaching excellent precision results in optical fiber alignment array fabrication – the crucial component in optical communication systems – resulting in low-loss, high-speed, large-capacity communication.

Laser micromachining, together with SLE which we use for fiber alignment structures production, offers definite advantages in terms of precision, consistency, speed, material versatility, and cost-effectiveness.

Features:

  • Ultra-high precision
  • Tight tolerances
  • Straight, flared, or with a cone for easier insertion
  • Designed for standard SMF fibers, diameter 125/250 µm (not limited)
  • High density, standard 0,25 mm pitch
  • Straight or angled holes

Arrays examples

Using our laser micromachining method, critical features such as tight tolerances, tight positional accuracies, and hole diameter – within the tolerance of ±0.25 μm – can be achieved. This tight control of metrics ensures well-controlled alignment that might reduce insertion loss and provide good repeatability.

Moreover, this method enables forming the hole entrance as a funnel, step profile, or with a conical taper for easy fiber insertion. The channels can be straight or angled (like 8̊ ).

Applications

The most common application of optical fiber alignment structures includes optical communication systems to transmit data over long distances with high bandwidth and low latency.

Optical fiber alignment arrays require precise alignment and positioning – the micro-holes formed in the optical fiber alignment array must be uniformly aligned and in a uniform pitch. The precision optical fiber alignment structures ensure that optical fibers are aligned accurately, providing reliable and consistent transfer of light and data.

Fiber connectors have incredibly tight tolerances enabling a low-loss connection. To achieve the tolerances, they must be handled and mated correctly.
