Building the third dimension of photonic integration

3D-fabricated optical interconnection platform that will scale photonic systems beyond alignment constraints

Vision

The Lightspring platform turns photonic packaging from a bottleneck into a programmable manufacturing step for industry-ready systems

  • Adaptability

    Lightspring is not bound by legacy footprints or specifications. Each connection is shaped to the component it serves — enabling layouts that adapt as designs change.

  • Precision

    Each single design is tuned along components’ material, geometrical and optical properties. Each structure is written at less than 0.1 micron tolerance and automatically aligned.

  • Speed

    Connections are written directly, in a single process step. What used to take days of manual alignment happens in one pass — enabling complex 3D architectures to take shape faster than before.

  • Scalability

    Our process is built to work across foundry recipes, materials, and use cases. The same core method can be replicated at scale, from a single prototype to an entire assembly line.

Technology

We route light in three dimensions, connecting photonic components into systems that scale.

Mode size converter and U-bend array

Lightspring enable new high-performance architectures by connecting chips, fibers and light sources in full 3D beyond classical assembly constraints.

Every connection is designed, characterised, qualified, and diagnosed as one solution, enabling powerful systems to transform industry.
