Glass fiber ferrules are foundational components in fiber optic packaging, ensuring that light is transmitted with minimal loss and maximum repeatability. At FEMTOPRINT, we fabricate high-precision ferrules with sub-micron tolerances, enabling ultralow-loss alignment between fibers or between fibers and chips.
Our ferrules are manufactured from fused silica or borosilicate glass, ensuring thermal stability and mechanical integrity.
What sets us apart:
Used in telecom, datacom, quantum devices, and sensor systems, our ferrules help customers reduce active alignment needs, increase reliability, and scale production efficiently through wafer-level microfabrication.
The fabrication of high precision V-grooves and hole arrays for 1D-2D fiber arrays for data-/tele-com faces technological challenges. This is due to the necessity of effectively handling dimensions from a few microns to a few millimetres with resolution and accuracy below 1 µm.
With the FEMTOPRINT laser-based micro-machining platform, high-precision fiber alignment elements can be fabricated with accuracy in dimensions and positioning better than 1 µm. It helps to enable 1D-2D fiber arrays with best-in-class product qualification in terms of losses according to telecom standards.
Thin to thick glass V-grooves and hole arrays.
Mechanical stability & surface flatness.
Customized hole arrays & V-grooves with additional assembly features.
Monolithic integration with other functions with self-alignment within +/- 1 µm.
Thermal stability and optimized thermal properties for integrated photonics.
