| contents | The significant growth of free-space optic communications and Light Detection and Ranging (LiDAR) is demanding gratings that emit highly collimated beams, i.e. with Rayleigh ranges of millimeters or even centimeters. Hence, weak-strength gratings, which radiate little amount of power per unit length, are needed. The main purpose of this work is to propose an efficient and accurate simulation tool to accelerate the design of weak-strength gratings required for these applications. To achieve this, we propose a simulator based on the classical perturbation method, which takes a circuit approach to the electromagnetic problem. Comparison with results obtained with a rigorous 2D full wave electromagnetic simulator (FEXEN) shows very good agreement with the advantage of decreasing simulation times by up to a factor $\times 16$ |
