In this work, we experimentally demonstrate metasurface-enhanced photoresponse in organic photodetectors. We have designed and integrated a metasurface with broadband functionality into an organic photodetector, with the goal of significantly increasing the absorption of light and generated photocurrent from 560 up to 690 nm. We discuss how the metasurface can be integrated with the fabrication of an organic photodiode. Our results show large gains in responsivity from 1.5× to 2× between 560 and 690 nm.
在这项工作中，我们通过实验证明了在有机光电探测器中金属增强光响应。我们设计并集成了一个具有宽带功能的金属超表面到有机光电探测器中，目的是显著增加 560 到 690nm 光的吸收和产生的光电流。我们讨论了金属超表面如何与有机光电二极管的制造集成。我们的结果表明，在 560nm 到 690nm 之间，响应率从 1.5 倍到 2 倍之间有了很大的提高。
