    摘要:

    设计了特定周期和占空比的非周期性高对比度光栅来实现光束的波前相位控制,进而实现对光束的多角度控制.在研究中,采用有限时域差分法模拟了特殊排列的非周期高对比度光栅,并获得了-10.644°,-21.176°,-28.307°,10.644°,21.447°和28.418°的光束控制角度.基于这种多角度控制的高对比度光栅阵列,提出了一种具有多角度光束控制的VCSEL光源,这种尺寸极小的宽角发射VCSEL光源系统能使激光雷达系统的结构紧凑化和微型化.

    Abstract:

    The non-periodic high-index contrast grating with a given period and duty was designed to manipulate the wave-front phase shift of the beam and further realize multi-angle beam steering. The finite difference time domain method was used to simulate the grating bars with a specific sorting order, and the beam steering angles of -10.644°, -21.176°, -28.307°,10.644°,21.447°, and 28.418° were obtained. Based on the multi-angle steering high contrast grating (HCG) array, a vertical cavity surface emitting laser (VCSEL) source with multi-deflection angle beam steering ability was proposed to meet the requirement of wide-field light detection and ranging (LIDAR) source. The tiny and easy integration of wide-angle emitting VCSEL light source system can cater to the compact and miniature LIDAR systems.
