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.
