应用于VCSEL的宽角度光束控制非周期性高对比度光栅阵列
Non-periodic wide-angle beam steering HCG array for application in VCSEL
摘要
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.关键词
