Abstract

Uniform grating couplers based on versatile L-shaped waveguides are experimentally demonstrated, with coupling loss of −2.7 dB and back-reflections of −20 dB. Apodized couplers with subwavelength-grating metamaterials predict improved fiber-chip coupling down to −0.46 dB within device layouts compatible with lithographic technologies available in nanophotonic foundries.

基于z形波导和亚波长光栅材料的亚分贝片外光纤耦合器

实验证明了基于通用l形波导的均匀光栅耦合器，耦合损耗为−2.7 dB，背反射为−20 dB。采用亚波长光栅超材料的Apodized耦合器预测，在与纳米光子代工厂中可用的光刻技术兼容的器件布局中，光纤芯片耦合可降低至- 0.46 dB。
