摘要

相控阵在通信系统中至关重要,在光电子学和光子学领域备受关注,可广泛应用于激光雷达、全息摄影和无线通信等领域。在这项工作中,我们提出了一种经过优化的炽热光栅天线,在工作波长为 1.55 µm 时,向上辐射效率高达 80%,占地面积仅为 3.5 µm × 2 µm。我们的数值研究表明,这种天线在 64×64 相控阵配置中能够产生理想的远场辐射模式。此外,我们的天线还具有-9.7 dB的低侧波水平和低于1%的可忽略反射效率,使其成为集成光学相控阵的理想候选天线。

An efficient compact blazed grating antenna for optical phased arrays
Phased arrays are vital in communication systems and have received significant interest in the field of optoelectronics and photonics, enabling a wide range of applications such as LiDAR, holography, and wireless communication. In this work, we present a blazed grating antenna that is optimized to have upward radiation efficiency as high as 80% with a compact footprint of 3.5 µm × 2 µm at an operational wavelength of 1.55 µm. Our numerical investigations demonstrate that this antenna in a 64×64 phased array configuration is capable of producing desired far-field radiation patterns. Additionally, our antenna possesses a low side lobe level of −9.7 dB and a negligible reflection efficiency of under 1%, making it an attractive candidate for integrated optical phased arrays.
