We demonstrated a compact and super-high resolution beam steering device 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 to 986 nm are 0.040° and 41°, respectively. These data indicate a number of resolution-points larger than 1,000, which is the highest number for non-mechanical beam deflectors ever reported.
