Abstract

Beam steering devices are widely used in laser radar, optical communication, free space optical interconnection and other fields. But at present, most beam steering devices are large in size, complex in structure and low in reliability, and then integration, portability and low power consumption of beam steering devices are the urgent problems to be solved in modern photoelectric system. This paper introduces a two-dimensional beam steering chip that integrates the liquid crystal optical phased array on the in-phased coupled Vertical Cavity Surface Emitting Laser (VCSEL) array. The theoretical model of beam steering chip is used finite difference time domain method to set up and simulate. The beam steering chip can theoretically achieve two-dimensional beam steering, with a max deflection range of 4.96°.
