电子控制的光束转向灵敏可靠。这对相位激光雷达的应用具有重要意义。报道了三元相干垂直腔面发射激光器阵列的实验特性，并实现了二维电子束控制。测量了束流的二维远场、近场方向图以及不同电流条件下束流的频谱。结果表明，光束转向是连续的和可预测的。阵列总功率的17.9%以上集中在中心瓣，耦合效率高。最大偏离正常值3.26°。从理论和实验两方面分析了三腔频率失谐的光束转向机理。
Electronically controlled optical beam steering is sensitive and reliable. It is significant for phased laser radar applications. We reported the experimental characterization of three-element coherent vertical cavity surface emitting laser arrays and demonstrated two-dimensional electronical beam steering. 2-D far-field patterns, near-field patterns, and the spectra of the beam under different current conditions were measured. It is demonstrated that beam steering is continuous and predicted. Above 17.9% of the total power of the array is concentrated in the central lobe, showing high coupling efficiency. Up to a 3.26° shift angle from normal is demonstrated. The beam steering mechanism of frequency detuning between the three cavities was analyzed via both theory and experiment.
