Continuous active beam steering with all-dielectric metasurfaces

Dynamical beam steering is crucial for various applications, including LiDAR and AR/VR. Previous approaches have demonstrated active beam deflection control, however, they typically rely on numerous deflectors, active material or complex integration with intricate circuitry. In this work, we introduce an innovative metasurface that enables continuous beam steering in tramsmission by simply altering the spot position of incident light. This approach offers a compact, cost-effective solution for advanced nanophotonic applications, paving a way for miniaturized optical systems.
