Fast Light Control Using BTO-Integrated Beam Steering
Active free-space beam steering relies on dynamically modifying the optical phase profile applied to a guided or free-space field. In integrated photonic platforms, this can be achieved through electro-optic modulation of the effective index within subwavelength structures. Barium titanate (BTO), with its large Pockels coefficient, enables efficient phase modulation in compact geometries. When incorporated into waveguides, metasurfaces, or grating-based emitters, BTO produces electrically controlled phase shifts that influence the far-field emission. Applying an external electric field adjusts the local refractive index with low latency, allowing real-time wavefront reconfiguration without mechanical components. These capabilities are useful in systems requiring fast and accurate free-space beam control. In LiDAR, free-space communication, and adaptive sensing, electronic steering supports rapid angular adjustments and stable alignment. Overall, BTO-based electro-optic devices offer a compact solid-state route to high-speed beam direction control.
