Simulador eficiente de antenas ópticas integradas con radiación en ángulos arbitrarios.

Abstract

The increasing interest in free-space optical communications (FSOC) and Light Detection and Ranging (LiDAR), requires gratings capable of emitting highly collimated beams, with Rayleigh distances in the order of centimeters or even meters. This requires the design of weak-strength gratings, which radiate little amount of power per unit length. In addition, dynamic beam steering is essential for these applications, enabling efficient environmental scanning and tracking of moving objects. This work aims to develop an accurate and efficient simulation tool to accelerate the design of weak-strength gratings, and study the effect of feeding light with arbitrary angles into the antenna. Comparison with results obtained with a full-vectorial 3D FDTD simulator, shows very good agreement with the advantage of decreasing simulation times by up to a factor of ×514.
