A compact and super-high-resolution beam steering device is demonstrated using a Bragg reflector waveguide. For 37-nm tuning in input wavelengths, we obtained a continuous beam steering angle of 60°. In addition, a divergence angle as small as 0.025 ° is recorded. The maximum divergence angle and steering range in the entire wavelength range of 958-986 nm are 0.040° and 41°, respectively. These data indicate a number of resolution points larger than 1000, which is the highest number for nonmechanical beam deflectors ever reported.
