Optical phased array antennas (OPAs) have significant potential for optical beam steering, which has the application to high speed optical wireless links. In this paper, the characteristics of a two dimensional OPA with a structure composed of 2× 2 and 4× 4 antenna elements are verified. Beam steering by wavelength tuning of-0.16/nm is measured and a required steering range of 1.97 is achieved within a-3dB coverage range of 5 in the theta direction and 7 in the phi direction.
