About
Lightspring is a French deeptech company that designs and manufactures optical interfaces for photonic integrated circuits using 3D lithography (two-photon polymerisation). It fabricates microlenses, 3D waveguides, and beam-shaping elements directly on chip to replace slow, expensive active-alignment packaging. The technology originates from research at the FEMTO-ST Institute in Besançon; co-founders include CEO Grégoire Bonnat, CTO Adrià Grabulosa, and Scientific Director Daniel Brunner.
