Beam steering in implant defined coherently coupled vertical cavity surface emitting laser (VCSEL) arrays is simulated using the FDTD solution software.Angular deflection dependent on relative phase differences among elements,inter-element spacing,element size and emitted wavelength is analyzed detailedly and systematically.We design and fabricate 1× 2 implant defined VCSEL arrays for optimum beam steering performance.Electronically controlled beam steering with a maximum deflection angle of 1.6° is successfully achieved in the 1 × 2 VCSEL arrays.The percentage of the power in the central lobe is above 39% when steering.The results show that the steering is controllable.Compared with other beam steering methods,the fabrication process is simple and of low cost.
