Planar optics and metalenses have moved rapidly from academic curiosities to practical technologies powering consumer devices, vehicles, and sensors. At the centre of this transformation stands PlanOpSim, a Belgian startup developing advanced computer-aided design (CAD) tools to make metasurface innovation scalable and manufacturable.

From Lab Curiosity to Industry Platform

Founded in 2019, PlanOpSim's genesis came from Lieven's insight while working on OLED display modelling. While academic researchers were experimenting with metamaterials, their workflows were fragmented, relying on disconnected simulations.

“I realized there was already a whole chain of methods that could be tied together in a workflow,” Lieven explained. “That could lead to a much more efficient design process.” Supported by the Flemish Innovation Fund and IMEC, Lieven built a prototype that laid the foundation for PlanOpSim's integrated software.
