How can we create LiDAR systems that are smaller, more stable and easier to manufacture at scale?
Traditional LiDAR often depends on moving parts or bulky optical assemblies, which limits robustness and increases cost. As applications across industry, robotics and future mobility demand compact and reliable 3D sensing, there is a clear need for LiDAR solutions that operate efficiently in a solid-state, chip-scale form factor.
Imec at Holst Centre uses an integrated photonics platform to develop solid-state LiDAR based on optical beamforming.
Instead of mechanical scanning, we use optical phased arrays that steer light on a photonic chip. This approach integrates the laser source, beam steering and photodetectors into a single, stable module. It reduces system size, improves reliability and enables manufacturing routes that support high-volume production. Integrated photonics also offers low optical losses, precise control of light, and the ability to scale functionality through chip design. To further improve the quality of the LiDAR signal, imec at Holst Centre developed complex software algorithms to compensate for fluctuations in laser and fabrication tolerances.
What is LiDAR?
Our focus
These capabilities open the way for LiDAR systems that fit into compact devices and industrial environments where robustness, size and manufacturability matter. The integrated-photonics approach provides a strong foundation for future sensing solutions across sectors that need accurate 3D perception in a stable and cost-efficient package.
