Glass Micro-components

As data transmission systems evolve toward higher speed and lower power, fiber-to-chip optical interconnects have become essential in advanced photonics. FEMTOPRINT enables this transition through custom glass microdevices that combine fiber ferrules, 3D waveguides, and micro-optical elements—all integrated in a single component.

Our glass micro-components allow for:

• Micro-mechanical fiber alignment features with micro- to sub-micron precision
• Complex 3D light paths within transparent substrates
• Efficient and compact beam shaping through free-form micro-optical elements
• Monolithic integration of several functionalities in devices and systems, which can be manufactured in volumes at wafer-scale
• Compatibility with standard assembly and packaging processes

These microcomponents are ideal for applications such as optical transceivers, PICs, quantum devices, and sensor systems, where space constraints, performance, and alignment precision are critical. With the ability to fabricate wafer-scale batches, we provide a highly scalable path from prototyping to mass production.

Applications of glass micro-components

Precision glass micro-components serve photonics, MedTech, watchmaking, quantum and space systems, providing miniaturized mechanical and optical parts with tight tolerances and excellent material stability.
