Abstract

Optical phased array is an important device for beam steering. To achieve the optical phased array which has wide steering angle, it is necessary the narrow antenna pitch. In this report, we proposed and investigated numerically the plasmonic waveguides antenna which has the low crosstalk for wide steering angle in the optical phased array. It was found that the crosstalk at the antenna pitch 800 nm of the gap type plasmonic waveguide can be almost ignored by the numerical simulation. The steering angle 156 degrees much wider than that of the conventional waveguides was achieved at this antenna pitch.
