Abstract
Optical phased array (OPA) has been widely employed across various applications, including light detection and ranging. Nevertheless, OPA faces significant limitations, such as excessive power consumption, complex control systems, and challenging packaging formats, which hinder its further development. Focal plane arrays (FPAs) have garnered increasing attention due to their absence of these drawbacks. However, FPAs currently face a dilemma as their ranging performance fails to meet application requirements. To address this issue, this paper presents a novel structure featuring small-scale receiving array and high directional antenna design. Utilizing this chip, we showcase a scanning range of 5.98° and a coherent detection capability of 6 meters.
