abstract = "We have designed and fabricated micro-LiDAR chips based on 1D optical phased arrays (OPAs) that collimate light in the horizontal direction only. Thus, a cylindrical lens is needed for the vertical collimation. A part of the work demonstrates the analysis of 1D beam steering experiments through the direct outcoupling from the waveguide facets with two straight cylindrical lenses available commercially and a detailed analysis based on the parameters like Rayleigh range and beam divergence is presented. This work also demonstrates the characterizations of 3D printed curved cylindrical collimating lenses. A thorough analysis based on the experimental work resulted in certain suggestions to improve the collimation and to perform the beam steering in a better way. ",
