title = "Fabrication-Friendly Ultra-Long Waveguide Grating Antenna for Silicon-on-Insulator Platform",
abstract = "Light detection and ranging (LiDAR) based on the optical phased array (OPA) on silicon photonics platform has been attracting intensive attention. Beam width and field-of-view are two critical design parameters for OPAs, which are determined by the length waveguide grating antenna (WGA) and the high packing density of the WGA array. However, the high index contrast on silicon-on-insulator (SOI) brings a great challenge to implementing long WGA and high packing density simultaneously. In this paper, we propose a fabrication-friendly WGA with weak perturbation strength achieved by placing subwavelength silicon segments around strip waveguide. Bound state in the continuum (BIC) is leveraged to suppress the sidewall emission. We theoretically and experimentally demonstrated a millimeter-long WGA with a feature size over 100 nm on SOI. A beam width of 0.13° is experimentally observed.",
