Light detection and ranging (lidar) sensors provide high resolution and high accuracy for diverse applications such as autonomous vehicles and three-dimensional imagers. Over the past few years, there has been significant development towards compact, lowpower, and low-cost realization of lidars. Recently, silicon-based large-scale optical phased arrays operating at around 1550nm [1-4] along with their application in lidar
