光学相控阵(OPA)器件在激光雷达、自由空间光链路、生物光子学等领域是必不可少的紧凑型固态光束扫描器。基于全氟化聚合物的独特性质，我们提出了一种具有低驱动功率和高光学吞吐量的聚合物波导OPA。与硅光子OPA不同，聚合物OPA能够在波束扫描期间实现可持续的相位分布控制，从而减少波束成形的负担。此外，通过结合由聚合物波导布拉格反射器组成的可调谐波长激光器，展示了二维光束扫描，这有助于激光集成聚合物OPA光束扫描器的发展。
Optical phased array (OPA) devices are being actively investigated to develop compact solid-state beam scanners, which are essential in fields such as LiDAR, free-space optical links, biophotonics, etc. Based on the unique nature of perfluorinated polymers, we propose a polymer waveguide OPA with the advantages of low driving power and high optical throughput. Unlike silicon photonic OPAs, the polymer OPAs enable sustainable phase distribution control during beam scanning, which reduces the burden of beamforming. Moreover, by incorporating a tunable wavelength laser comprising a polymer waveguide Bragg reflector, two-dimensional beam scanning is demonstrated, which facilitates the development of laser-integrated polymeric OPA beam scanners.
