Abstract: We demonstrate a 32-wire optical phased array with a compact and simple optical antenna. It achieves a lateral (Psi axis) scan of +/- 48.5 degrees by phase modulation with a beamwidth of 2.3 degrees x 2.8 degrees. In addition, the proposed OPA can also achieve longitudinal (theta axis) scanning by adjusting the operating wavelength. When the wavelength is changed from 1.5um to 1.6um, the spot is steered 17.1 degrees in the longitudinal axis.
