高效的光子耦合器是将量子发射器耦合到量子光纤网络的可扩展平台的必要组件。我们反向设计的耦合器用于砷化镓薄膜光子学，与砷化铟量子点兼容，砷化铟量子点是最高质量的量子光源之一。我们根据11种不同的设计制造并测试了至少4种设备。在单模光纤光学装置中，所有反向设计的结构都优于传统的光栅外耦合器。使用一种新的套筒和批量制造方法，允许一个较小的允许的最小特征尺寸约束的逆向设计优化协议。采用这种新的设计约束，提高了平均器件传输效率从17.4%到27.5%。宽带优化标准的使用并没有导致实际带宽的静态显著改善，但确实降低了测量带宽的方差，这表明设计更稳健。
: Highly efficient photonic couplers are a necessary component of a scalable platform to couple quantum emitters into quantum fiber networks. We inverse-designed couplers for use in gallium arsenide membrane-based photonics that are compatible with indium arsenide quantum dots, one of the highest quality quantum light sources available. We fabricated and tested at least 4 instances of devices following 11 different designs. All inverse-designed structures outperformed the traditional grating outcoupler in a single-mode optical fiber optical setup. Using a novel sleeve and bulk fabrication method allowed for a smaller allowable minimum feature size constraint in the inverse design optimization protocol. Employing this new design constraint improved the average device transmission efficiency from 17.4% to 27.5%. The use of broadband optimization criteria did not result in statically significant improvement in actual bandwidth, but did decrease the variance in the measured bandwidth, suggesting a more robust design.
