Optical beam steering can find applications in several domains such as laser scanning, LiDAR (Light Detection And Ranging), optical switches and interconnects. Present beam steering techniques such as liquid crystals or MEMS-technology are limited in speed and/or performance. Therefore we have studied the possibilities of the silicon photonics platform in beam steering applications. In this paper, we have investigated a 16 element one-dimensional optical phased array on silicon-on-insulator with a field-of-view of 23°. Using thermo-optic phase tuners, we have shown beam steering and shaping over the complete field-of-view. This clearly shows the potential of silicon photonics in beam steering applications.
