Visible light communication (VLC) is a promising candidate for high-speed wireless communication with numerous unlicensed spectrum. To achieve high-speed data communication, it requires intense light signals concentrated on a tiny fast photodiode. The common way of using focusing optics reduces the field of view (FoV) of the photodiode due to the conservation of étendue. Luminescent solar concentrators (LSC) provide a solution to enhance the signals without affecting the FoV. In this paper we demonstrate nanopatterned LSCs fabricated on flexible plastics that achieve a doubling of optical gain compared to its traditional rectangular counterparts. These LSCs can free VLC detectors from complex active pointing and tracking systems, making them compatible with smart mobile terminals in a simple fashion.
可见光通信(VLC)是一种极具潜力的高速无线通信技术,具有大量未授权频谱。为实现高速数据通信,它需要将强光信号集中在一个微小的快速光电二极管上。由于光通量守恒,使用聚焦光学器件的常见方法会减小光电二极管的视场(FoV)。发光太阳能聚光器(LSC)提供了一种在不影响视场的情况下增强信号的解决方案。在本文中,我们展示了在柔性塑料上制造的纳米图案LSC,与传统的矩形LSC相比,其光学增益提高了一倍。这些LSC可以使VLC探测器摆脱复杂的有源指向和跟踪系统,以简单的方式使其与智能移动终端兼容。
