In this paper, we have demonstrated the beam steering experiments with the help of our optical phased array devices. The lateral beam steering has been showed successfully with the wavelength through the tunable laser source. The number of output channels were 512 and the array width was kept more than a millimeter with a 2-µm pitch. The beam steering angle has been measured as 45° and the beam movement was 1°/nm. As the chip does not collimate the beam vertically, so, a commercial collimating lens has been used in the vertical direction.
