Article Synopsis
- - Recent advancements in photonic technologies have significantly reduced costs for manufacturing automotive sensors, particularly lidar systems.
- - Most current lidar systems rely on direct detection time-of-flight (ToF) sensors at 905 nm, which use mechanical mirrors for beam steering, but they have several limitations.
- - Key drawbacks include eye-safety concerns that restrict laser power and range, potential interference in crowded environments, and the bulky design of mechanical scanners that complicates integration into modern vehicles.
This paper reports on large field-of-regard, high-efficiency, and large aperture active optical phased arrays (OPAs) for optical beam steering in LIDAR systems. The fabricated 5 mm-long silicon photonic OPA with a 1.3 μm waveguide pitch achieved adjacent waveguide crosstalk below -12dB.
