Lightspring

Product and customers

LightSpring uses direct-write 3D lithography to fabricate optical connections between photonic components. The process automatically aligns each interconnect to the materials, geometry and optical properties of the chip, fiber or light source, with the company reporting sub-0.1-micron tolerance.

The platform is designed for photonics and optical-hardware manufacturers facing a difficult chip-integration step. LightSpring is moving the process from laboratory work toward production, with the aim of making photonic integration more repeatable and scalable.
